  • What's 3d printing metal powder? 3D printed powdered metal is different than general 3D materials. This is because it's a good plastic and can meet the requirements for small diameter, high ball form, fluidity, density and narrow particle size distribution.

    Principal uses for metal powder in 3D printing
    It is used extensively in 3D printing metal powder especially in aerospace, which has been vigorously developed. 3D printing metal powder also has applications in dentistry, automotive and medical fields. This material can also be used to produce customized implants, advanced medical devices and other items by doctors.
    Performance requirements for 3D Printing Metal Powder
    Pure degree. A final assembly with ceramic inclusions can significantly lower its performance. They are generally hard to melt and difficult to sinter so it is important that there be no ceramic inclusions. The powder fluidity and the loss loading density must also be carefully controlled. Powder fluidity is directly related to the stability and uniformity of powder delivery in the printing process. Powder morphology, powder size distribution and loose packing density all affect the fluidity. Fluidity increases with larger powder particles. Particle size distribution and proportions of extremely fine powder are more consistent. While the particle density is stable, relative density rises and powder fluidity also increases. The particle surface adsorption will decrease powder mobility. Powder particle size distribution is also affected. There are different 3D printing processes and equipment that require powder particle distribution. The 3D printers can use different energy sources to divide metal powder into smaller particles. This includes the metal printer with laser, powder printer using electron beam, and metal printers that have a powder printer. It is directly related to how the powder was prepared. Powder particles that are made from metal gases or molten liquids to powder tend to be round. Powder particles can vary from powder to solid. Most powder obtained by electrolysis with aqueous solution is, however, dendritic. In general, powder particles that are more fluid than others will have higher sphericity.
    The importance of 3D metal powder printing
    3D printing with metal powders is quicker and allows rapid prototyping. Manufacturers can modify designs more quickly. Because the 3D metal printer only uses the necessary material, this approach can be cost-effective. It makes it simple to create complicated machine parts, and allows for the production of difficult parts.
    Prices for powdered metal 3D printing
    It is not uncommon for the price to vary depending on how pure 3d printing metal powder is. In the process of changing, 3d printing material powder's market price is also dynamic. Our company website provides information about the current price of 3D printing metal powder. We are available to assist you with any question.

  • Is boron a metal? Boron powder, which isn't a metal is solid non-metal. It doesn't have all the characteristics of metals. Boron, the only nonmetallic element, has an outermost layer with less than 4 electrons. It can exist in both amorphous or crystalline form. While the first is brown-black, it can also be found as a powder. The second is metallic and black-gray. Its hardness is comparable to that of diamond. The amorphous form of boron gradually oxidizes in the air at room temperatures and ignites at about 800°C. Even after being boiled, Boron, hydrochloric or hydrofluoric acids will not work.

    You can slow erode and then oxidize Boron with a mix of hot concentrated and mildly acidic sodium dichromate as well as sulfuric acid. The slow oxidization process of crystallized boron can also be done by ammonium persulfate, hydrogen peroxide, and ammonium dichromate. Boron reacts strongly with sulfur at around 600°C to create a mixture of Boron sulfide. The formation of boron-nitride occurs when boron is heated above 1000°C in nitrogen or ammonia. Between 1800 and 2000 C, hydrogen and boron do not react. Boron and silicon, however, react between 2000 and 2500 C to create silicon boride. To form metal borides, boron can react with many metals or metal oxides at very high temperatures.

    Boron Properties:
    If the elementalboron has been oxidized in the air, it turns to a blackish or brownish powder. The boron trioxide films are formed when the internal boron continues to oxidize. Fluorine reacts at normal temperatures and it is not corroded with hydrochloric and hydrofluoric acid in aqueous solution. Boron is not soluble in water. Powdered boron can be easily dissolved in boiling sulfuric acid or nitric acids. Powdered Amorphous Boron is highly explosive.

    Boron can conduct electricity at low temperatures but is weak at high temperature. You can find a wide range of different allotropes in elemental Boron. For example, the brownish crystalline and amorphous forms of boron. Although elemental boron's hardness is comparable to that of diamond, it also has an electrical resistance and high temperature. But its electrical conductivity goes up with increased temperatures. While crystalline boron tends to be more stable, amorphous or active boron can perform better. One of the 14 boron isotopes, only two being stable, are amorphous boron. Boric acid in nature and borate in nature are two of the most common forms of boron.

    Boron Uses:
    Boron is necessary for ribonucleic Acid formation. Ribonucleic Acid is an essential building block of all life. James Stephenson, postdoctoral researcher from the University of Hawaii's NASA Institute of Astrobiology said, "Bronze could be crucial for the origin of human life." He explained that it stabilizes nucleic, an important component of ribonucleic, and thus may have been important in the formation of the first species of life. Ribonucleic acids is thought to have been a precursor for information in DNA during early life.

    Boron is a common chemical raw mineral. It's used to make borax and boric acid, boron compounds and elemental Boron. You can also use it in the metallurgy industry, machine, building materials and machinery. Boron powder, whether used in a compound or additional to the alloy, is regarded as an essential starting material.

    Boron can be used as a raw material in high-purity, high-purity, boron-halides manufacturing. Boron powder is used in the preparation of many borides. This can save valuable and olefin-deficient materials. Additionally, boron can be used as a catalyst for organic chemical reaction.

    Luoyang Tech Co. Ltd. (a professional Boron powder producer) has over 12 years of experience in chemical product research and development. You can contact us to request high-quality Boron powder.

  • British media reports that scientists made an important breakthrough: the conversion of radio waves into electricity. We may soon be able, for perhaps a lifetime in the not too distant, to have battery-free phones and battery-free laptops.
    MoS2 (a novel two-dimensional material) is one of the world's thinnest semiconductors. It is a two-dimensional semiconductor material with photoelectricity and diamagnetic properties. This semiconductor can also be used in a linear photoconductor as well as an N-type and P-type semiconductors with rectification, exchange.

    According to the British Daily Mail, scientists have created a "silicon rectifier-diode antenna", which can charge smart phones and notebooks with battery-free electricity.

    According to this report, although all antennas have the ability to generate electricity, it is not common for them to produce large amounts of electricity. The study found that a silicon rectifier antenna generated approximately 40 microwatts in power under a 150-microwatt WiFi signal. These lights, experts claim, are sufficient to activate the mobile phone's chip or illuminate the display.

    To make the most of radio waves, electronics enthusiasts must also be aware that high-frequency alternating current is generated by radio waves. This current needs to be converted by an electronic rectifying and filtering apparatus to become direct current. Molybdenum Disulfide is one of them.

    Also, does this molybdenum disulfide exist? Everyone is familiar with graphite. Molybdenum dioxide has a hexagonal, multilayered structure that is similar to graphite. Molybdenum disulfide or MoS2 is a novel two-dimensional semiconductor. This material has photoelectricity and semiconductor properties. It can also be used as a line photoconductor. Can work. This allows it to be used in the production of silicon rectifier antennas.

    Molybdenum disulfide, in fact, is a rising star in material science both here and abroad. why? MoS2 also happens to be one of the best solid metal lubricants. Since the mid-19th-century, MoS2 has been used to lubricate carriage bearings. China became the third country to have molybdenum diulfide nanosynthesis technology in 2015 when a local lubricant firm developed an automobile molybdenum nanolubricant.

  • Properties of ceramic silicon carbide The high hardness of Silicon Carbide Ceramics is high, with a high melting point (23400), good wear resistance and resistance to corrosion, and also excellent chemical stability, thermal shock resistance. This makes it a popular choice in many fields, including energy, metallurgy and machinery, as well chemical, aeronautics, defense, and petroleum.

    You can choose between black and green silicon carbide
    Abrasive industries often divide silicon carbide in black carbonized leel and green silica according to its color. These are both hexagonal crystals that belong to a-SiC.

    Black silicon carbide has a siC content of about 98.5%. Black silicon caride is made up of petroleum coke, quartz sand, high-quality silica, and petroleum coke as its main ingredients. The material is then melted at high temperatures by an electric furnace. It has hardness that is similar to diamond. Also, its mechanical strength is much higher than corundum. It is tougher than green silicon caride. This is why it is most commonly used in processing materials of low tensile strengths, like glass, ceramics, stone and cast iron.

    SiC content in green silicon carbide is greater than 99 percent. It is made up of high-quality silicona and petroleum coke. You can add salt to make it more smeltable and then melt in a high temperature furnace. It can be used to machine hard alloys, alloys and optical lenses. You can also use it to create wear-resistant liner cylinders and fine-grained, high-speed tools from steel.

    Ceramics made of silicon carbide

    SiC's covalent bond is strong, which leads to a variety of exceptional properties in SiC ceramics. But it makes it difficult for SiC ceramics to sinter. It is difficult to sinter SiC ceramics because the covalent bond between SiC and SiC is too strong. The sintering temperature must be raised to compensate. It also increases costs and makes it less useful in the industry.

    According to thermodynamics, densification can be driven by the loss of energy from the original powder during sintering. The SiC grain boundary's free energetic is high. This causes a decline in the powder's energy even if it becomes a solid solid interface. The driving force behind the sintering procedure is lessened the larger the difference in the free energy. The SiC powder can be more difficultly sintered than other ceramics. The common practice is to add sintering additive, reduce the powder size, and pressurize. This will change the free energy of the powder and encourage SiC to be densified.

    According to kinetics, there are five main mass transfer mechanisms involved in the sintering of materials. These include evaporation and condensation, surface diffusion, viscous circulation, surface diffusion, grain border or lattice diffusion, as well as plastic deformation. Because SiC has a strong covalent link, it results in a slower solid-phase mass transport rate like surface diffusion and lattice distribution. However, gas phase mass Transfer requires high temperature to facilitate powder decomposition. SiC's decomposition temperature is approximately 2500°C so it is not possible to use gas phase mass transfer for ceramics density. To achieve viscous flow, existing sintering processes add a sintering help to either increase SiC's solid phase diffusion rate or create a liquid phase-assisted SiC.

    SiC ceramics have a high purity and are capable of increasing the thermal conductivity. Sintering aids are needed to lower the sintering temperatures and increase the density. High thermal conductivity SiC ceramics can be sintered to resolve the contradiction. Priorities and challenges
    The sintering temperatures of Al2O3 ceramics are low, they have low costs and excellent electrical insulation. These ceramics have been used extensively, however, they possess low thermal conductivity, making them ineffective for high-power circuits.

    BeO ceramics possess good dielectric qualities and can be used in high-heat conducting fields as substrate materials. BeO is toxic and Europe, Japan and America have issued regulations to limit the development and sale of electronic products.

    AlN ceramics offer excellent thermal insulation, low electrical insulation, and low dielectric constant. This makes them ideal for high power circuits. AlN ceramics' sintering temperatures are too high. Because of this, it is difficult to prepare and expensive. It has also not been used in large scale production. AlN can also be subject to the hydrolysis reaction and is not reliable in moist environments.

    Low density SiC ceramics offer high mechanical strength and low oxidation resistance. They resist chemical corrosion and are well-developed in the area of electronic products. They can also meet future demands for small sizes, high reliability, high efficiency, and light weight of electronic devices.

  • According to zhaomeng, China international graphene resources alliance deputy secretary general, market views show that the graphene market in China has not been "hot enough" to bring down the fever and that it should remain "hot".

    Graphene can be described as an allotrope form carbon. It is composed of just one layer of carbon atoms, in a 2-D hexagonal lattice. Each vertex has an atom. It is also the main structural element for other allotropes such as graphite charcoal carbon nanotubes fullerenes.

    The graphene sector is showing good signs of development.

    China economy times: It was learned that China places great importance on the graphene sector. In 2014, President xi jinping visited jiangsu's graphene material research institute. He also visited the UK graphene research center at Manchester University in 2015. Harbin graphene technology show in 2016 is another example of China's current graphene industry.

    China's graphene sector is in an excellent position at the moment, with ten thousand businesses' innovation, and fierce competition. According to the most recent statistics from in-depth market research, strategic planning analysis and report on graphene sector released by Qianzhan industry researcher institute, China's graphene market is projected to grow to 56 billion yuan for 2019 and to rise to 236.5 billion yuan for 2022.
    It is necessary to overcome three key weaknesses.

    China economic times. In your opinion, which are China's weaknesses in the graphene industry?

    Zhao said that China still has many unmet needs in graphene development. The following three areas should be considered first.

    First, resource imbalance.For example, China's Yangtze river delta, guangdong-hong kong-macao greater bay area and beijing-tianjin-hebei region have advantages in talent, technology and capital. Technology has improved rapidly but there is limited environmental capacity. There are also few graphite resources.

    There is also little international collaboration. Over the past few years, China has seen a rise in BBS and exhibitions at all levels. Additionally, some enterprises and regions have brought new technologies and talents to China. Unfortunately, promotion is slow and inefficient. The scope and quality of cooperation must be increased.

    Dritte, the industry standards remain behind.

    The charge rate of the graphene smartphone is currently 40%. However, it does not have the same effect as the original smartphone.

    Battery technology currently stands as a major obstacle in the development and promotion for electric cars. The graphene-based energy storage device will make a huge impact on the development and promotion of electric vehicles. Large-scale commercial usage may not be possible until 2020 according to the optimistic outlook.

  • What does aluminum nitride mean? Covalent bond compounds are made from aluminum nitride. This atomic compound is non-toxic and can be found in white, grayish, or white atoms. Aluminum nitride formula AlN. AlN is an aluminum nitride that can be treated with metal. It can also replace tantalum and alumina oxide in many electronic instruments. Aluminium nitride is made by either reduction of aluminum oxide, carbon, or direct aluminum nitride.

    Properties of ceramic aluminum nitride
    High purity, low particle size, high activity and good purity make the aluminum nitride clay powder a great raw material. This ceramic aluminum nitride substrate exhibits high thermal conductivity, low expansion, strength, chemical resistance and low dielectric losses. This makes it an excellent large-scale heat sink substrate for integrated circuits as well as a packaging material. It is an innovative type of ceramic material that can withstand wear, and has hardness levels higher than traditional alumina.

    More information about the ceramic substrate for aluminum nitride:
    China is renowned for its long-standing history in the development of substrates. The number of available substrates has increased over time. Fiber substrates, FR-4 and aluminum substrates are the traditional types of substrates. Copper substrates are also available.

    The improvement of industry requirements is limited by thermal expansion coefficient matching and heat dissipation. When these new needs are not being met, they have to begin to search for alternative substrates.

    A ceramic aluminum nitride substrate made using LAM technology, which is laser high-peed activated metallization, makes a great choice. The metal layer can be more closely bound to ceramic and it has a high bonding strength. The ceramic pieces larger than one mm in height can have a maximum strength of 45, Pa. An aluminum nitride substrate contains a metal layer layer that has higher and firmer resistance. It can also be customized in thickness from 1 mm to one mm.

    Is it because aluminum nitride ceramic is more expensive than the other substrates?
    Comparable to the ceramic substrate, aluminum-based substrate has a thermal conductivity between 1 and 2 W/mk. The copper's thermal conductivity is 383.8W/mK. But the thermal conductivity is just 1.0W/mK. This is better. 1.8W/mK. Ceramic substrates made of aluminum nitride have a lower thermal conductivity. Data ranges between 170 and 230 W/m.k.

    The coefficient of thermal extension (CTE) is an example. For LED lighting, CTE for the main substrate is between 14 and 17ppm/C. The CTE for the silicon chips is 6,ppm/C. If there's a temperature differential or drastic temperature change, the PCB can expand beyond the capacity of the package. The problem of soldering can result. CTE is the CTE of an aluminum nitride-ceramic substrate at 4-5ppm/C. It is therefore brighter and more in line with the chip's expansion ratio and is effective to prevent similar problems.

    Furthermore, aluminum nitride ceramic substrate is free of organic components. The copper layer doesn't contain any oxide layers. This layer has a long life span and can be used in a reduced atmosphere for long periods.

    These aluminum nitride ceramic sub-substrates are very popular in the marketplace. Because of their low frequency loss, low dielectric constant and easy design, it is possible to build high-frequency circuits and perform high-density line/pitch assembly (L). A resolution of up to 20mm can be achieved. The current trend towards light and small favors the small, slim, light, and thin.

    Exports of ceramic substrates make up the majority of their production. To realize the localization and growth of aluminum nitride ceramics substrates in domestic markets, independent research has been a key factor. Domestic PCB manufacturers have also paid closer attention. There are many benefits to aluminum nitride substrates.

  • First, nanowires will replace infrared
    Due to rapid development in the display industry, and the high cost of ITO-conductive films and limited resources of indium, industry is looking at alternative options such as nanowires, metal grids or carbon nanotubes. Silver nanowires have a higher technology-process maturity ratio than other alternative materials. Additionally, the flexible nature of silver nanowires makes them a viable alternative to other conductive materials.

    Nanosilver metal is the primary material used to make Nanosilverwire. Due to its unique features, Nanosilver wire exhibits excellent antibacterial abilities, safety, and non-pollution which can be used in many areas.

    Silver nanowires, as a replacement for infrared contact technology, will be utilized in large-scale applications with the current process. Du said that "the substitution is already very evident." The large-size silver nanowire products have won customers' attention, especially in an electronic whiteboard market that is forecast to grow rapidly in 2019.

    Infrared touch control has been the most popular method of controlling electronic whiteboards. Infrared receiver tube and infrared transmitting tubes are set in raised borders to make an infrared optical system on the screen. The screen then realizes positioning and touch control.

    2020 will be the next big flashpoint

    It is well-known that silver nanowires must be mainstreamed in small and medium-sized markets.

    Silver nanowires can be used to replace ITO-conductive films due to the global slowdown in smartphone sales. "Whether you're looking for facial recognition or a full screen display, the smartphone market needs innovative innovation," du stated.

    Step 3: Breaking through the nanowire

    Silver nanowires, which are ITO alternatives materials, have been in the spotlight for some time. Many enterprises have done research, developed and invested, however, this technology is not yet widely used. The production, storage, patent, manufacture, storage, preservation and patent of silver-nanowires are all important considerations that limit their growth.

    Silver nanowires cannot replace ITO-conductive films completely. It is not realistic to replace ITO conductive films completely.
