ws2 oil additive is a pioneering anti-friction and anti-wear nanotechnology engine oil additive based on proprietary patented technology developed at the Weizmann Institute of Science. The additive's lubricious properties are due to inorganic, fullerene-shaped Tungsten Di-sulfide nano particles that reduce friction and heat and create continuous tribofilm coating on moving engine parts. This unique continuous tribofilm is especially efficient under extreme pressure and temperature conditions.

Using a four-ball friction tester, samples of ws2 powder were mixed with a base oil to form sample oils with different mass ratios and then the tribological behavior of each oil was investigated. The morphology of wear scars on the friction surfaces was also studied.

The results show that WS2 at a low concentration of 1%, 90 nm in the sample oil can effectively decrease the coefficient of friction (COF) and abrasion loss. However, the WS2 particles are prone to exfoliation when it is applied to the surface of the friction pair under normal load and the action of shear force. As the exfoliated WS2 molecular layer remains on the pits and peak tips of the friction surface, it may directly contact and collide with the friction surface to form a wear furrow, which may appear more clearly in the sample oil with 1%, 90 nm WS2. The samples with ionic liquid as a solvent can better integrate the WS2 and the base oil, which can reduce the reunion between the nanoparticles.

stearic acid emulsion is an effective stabilizer, thickener and softener that helps to create a rich lather for shave foams. It also has occlusive properties that help to keep the skin hydrated and prevent moisture loss.

A stearic acid soap is a type of O/W emulsifier containing palmitic and/or stearic acids, optionally incorporated with other oil-soluble components such as waxes, oils or fatty alcohols. The proportions of the oils and fats are designed such that the aqueous phase is dispersed finely in the oil phase, thus forming an O/W emulsion.

The stearic acid soaps used for O/W emulsions can be prepared by the saponification of palmitic and/or stearic acid with one or more saponification bases. These are usually lauric, myristic, stearic and/or heptadecanoic acid.

Technical stearic acids are obained by the saponification of tallow and are generally comprised of 50% to 55% palmitic acid, 40% to 45% stearic acid, and small amounts of other C12-C22 fatty acids such as lauric, myristic, pentadecanoic, heptadecanoic, oleic, linolenic or erucic acid. In order to increase the rheological stability of the O/W emulsifier, these fatty acid soaps may be mixed with other components such as oil-soluble waxes, oils or fatty alcohols.

In the present study, nanocrystalline cellulose (NCC) was grafted with lauric acid, palmitic acid, and stearic acid and used as a stabilizer to prepare styrene-butyl acrylate emulsion. The emulsions were characterized for their pH, dilution, Ca2+, and centrifugal stability. The mechanism of a modified NCC (MNCC) stabilized emulsion was investigated using transmission electron microscope and zeta potential, which revealed that long-chain fatty acids were well grafted onto NCC by esterification initiated at low temperature.

Calcium Nitride Ca3N2 is an inorganic compound with constituent elements calcium and nitrogen. It has various isomorphous forms, out of which a-calcium nitride is more commonly encountered. It has a strong chemical activity and can be used for obtaining reactive nitride ions, such as the niobium tricarbonate and hafnium trichloride.

In IUPAC nomenclature, calcium nitride is called calcium azanidylidenecalcium and represented by the formula Ca3N2. It has different properties and can be obtained by reacting elemental calcium in a pure nitrogen stream or heating distilled fibrous metallic calcium purified by distillation to 450 degrees Celsius for 34h in pure N2 gas flow.

The oxidation number of Ca in Ca3N2 is (c)+2 because atoms of calcium in a +2 state combine with atoms of nitrogen in a -3 state to give a net zero charge, as the +6 charges of the calcium atoms cancel out the -6 charges of the nitrogen atoms. It is a soft, reactive metal that is often alloyed with aluminum and beryllium and serves as an important part of industrial and biological materials such as cement, mortar, bones, teeth and shells.

When writing a name for an ionic compound, it is essential to follow two rules. One is that the nonmetal must be listed first, and the second is that the oxidation state of the metal must be indicated by a parenthesized Roman numeral.

Zirconium boreide, a chemical substance that has the molecular structure ZrB2, is one example. Zirconium boreide is a grey-gray crystal. The three main components of zirconium-boride are zirconium monoboride and zirconium dimoride. The stability of zirconium boride in wide temperatures is limited to the diboride. Zirconium boride is used mostly in industrial production.

Zirconium diboride properties:

Zirconium boride can be found in hexagonal crystal forms, as well as gray crystals or powders. It has a relative density of 5.8 and a melting point of 3040. Zirconium diboride exhibits high resistance, strength and stability at elevated temperatures.

Zirconium boreide is metallic and has an electrical resistance slightly less than the metallic zirconium. The material is stable over a large temperature range once heated. Although its melting point is very high, zirconium-boride can be sintered at much lower temperatures. By combining metal zirconium with the boron carbide, boron nitride, and heating to 2000 degrees C in an argon flow, zirconium boride can be prepared.

Zirconium boreide is one common material in Boride. ZrB2 features a high melting points, good stability, and high resistance to corrosion. This material is often used to make high-temperature functional and high-temperature materials.

Use of zirconium-boride in ZrB2-C reactors

While it is now much more resistant to molten iron erosion and spalling than before, there is still some problem with strong erosion and an accumulation of alumina. ZrB2 is a ZrB2 product that uses ZrB2 materials to resist molten iron erosion. It also has good performance at high temperatures. C-ZrB2 quality, nozzle protection rings. ZrB2 is high-temperature oxidized to produce a low melting liquid phase B2O3. The reaction with Zr0 increases the viscosity and corrosion resistance.

Use zirconium-boride in Mg0-C reactors

You can either add ZrB2 into Mg0-C or use ZrB2 directly as an aggregate, powder or fine powder for refractory bricks or castables. This is because ZrB2 has a higher antioxidant activity at moderate temperatures than A1. When the temperature is low, the liquid phase starts to form. The MgO particles condense on it and eventually forms a reactionant. If the temperature rises above 700°C, condensate containing B2O3 is formed. This condensate acts as an antioxidant, hinders oxygen's diffusion, and acts as a protection layer. The advantages of adding A1 for antioxidants are evident at higher temperatures. B2O3 is not able to evaporate at high temperatures, which can cause its antioxidation properties to be weakened.

Use of zirconium-boride in A1 and C refractories

ZrB2 has been added as an antioxidant for A1-C materials. This can have a great effect on between 700-12000. Also, because of formation of low-temperature liquid phases (B2O3*A1 Molten Phase Oxidized by ZrB2), this anti-oxidation mechanism can be about the same as that for Mg0-C. Additionally, an oxidized sample contains the 9A1*B2O3 crystal phases with a melting points as high at 1965. Low temperature and the initial condensation of this liquid phase can produce high-temperature products and higher erosion resistance.

The product will perform significantly better in terms of oxidation resistance as well as corrosion resistance.

ZrB2 Zirconium Diboride Ceramic Material can be used not only as an exceptional refractory, but also in space shuttles and missiles, which will improve the material's high-temperature resistance, safety, and performance.

ZrB2's low resistivity makes it suitable for electrode and contact materials. It is suitable for use in the electrodes of high-temperature heating devices and metal thermocouples.

Zirconium boreide has a high degree of hardness and is therefore very durable. It can also be used to make cutting tools.

Zirconium Diboride Powder has a very high melting point, strength and conductivity, as well as a positive conductivity coefficient and a low thermal expansion coefficient. Additionally, it has exceptional chemical stability, trapping concentrator and smoldering properties.

Mis-asia (Advanced Material Tech Co., Ltd.) is a leading manufacturer of zirconium boride. We have over 12 years' experience in developing chemical products and research. We are happy to assist you in your search for the highest quality zirconium bore.

Tungsten carbide, or Tungsten Carbide is a combination of tungsten (carbon) and other elements. The molecular formula of WC is 195.85.

It's a hexagonal black crystal that has a metallic luster and hardness very similar to diamond. It's a great conductor of heat and electricity. Tungsten carbide can't be dissolved in water, hydrochloric, or sulfuric acids. However, it is easily soluble and dissolves in mixed acid of hydrofluoric acid and nitric acid. Pure tungsten carbide is fragile. Tiny amounts of cobalt or titanium can reduce brittleness. Tungsten carbide can be used to cut steel by adding titanium carbide, tantalum caride, or any combination thereof. This improves the anti-knock ability. Tungsten carbide has stable chemical properties. Tungsten carbid powder is used to produce cemented carbide.

There are two kinds of carbides that can be made by the tungsten carbon binary system: W2C or WC. Among them is WC, which is used as the raw material to make cemented carbide. It also serves as a raw material powder that is essential in order to prepare high-wear coatings for thermal spraying. WC exhibits high hardness and an unusually high temperature hardness. Co can wet WC. Ni. Fe. WC. WC* is wettable by cobalt melt. If the temperature rises above the metal's melting point, then WC is easily dissolved. However, when heat is decreased, WC is capable of precipitating. You can use these excellent properties to make cobalt and nickel the binder phase materials. Then, sinter or coat at high temperatures to produce a wear-resistant coating.

Its weak resistance against high-temperature oxidation is the main drawback to WC. It will oxidize in air between 500-800 degrees Celsius. But it can quickly be resolved by W2C and carbon when exposed to intense heat. You can pre-protect the WC particles using a heat-resistant, oxidation resistant metal as the layer or bonding phase. It is also possible to solidify it with TaC and TIC. Composite carbides can be formed to enhance the heat-resistant or oxidation-resistant characteristics of WC. WC can be heated up to 2850 degrees Celsius under Ar conditions, but it is stable and does not react with high-temperature nitrogen.

W2C has higher melting points and harderness than WC. With WC, it can be formed into a W2C+WC electroctic combination. Because it has a lower melting point, casting is simple. You can call it "cast-tungsten carbide" or "fusibletungstencarbide". The mass is approximately 3.8%20%, which includes 78%80% and 20%22% respectively of W2C (mass), and WC (mass). Cast tungsten carbid is an inexpensive, hard-wearing material.

The WC powder can be combined with iron-, nickel, and cobalt-based self-fusible powders as well as nickel-aluminium composite powders. It is commonly used for the preparation of high-wear-resistant coatings. Tungsten carbide powder is mostly used for thermal spraying a wear-resistant coat. While protective atmosphere plasma spraying and vacuum plasma spraying are possible, adhesion to the sheet may not be as good.

According to scientists, this reaction can achieve a total PX yield of up to 90%. You can get a maximum yield of 90% in this PX reaction.

Petrochemical products require essential aromatic hydrocarbons. PX, which is the most essential aromatic hydrocarbon, is the primary chemical raw material used to produce three important synthetic materials: synthetic resin (synthetic fibre), synthetic rubber (synthetic rubber). In order to address the shortage of PX, the research group is committed to developing and using renewable biomass resources. The team chose to transform aromatic hydrocarbons products into PX, as well as to create a high-selector synthetic route, from biomass to toluene.

Acrolein was chosen by the researchers as the biofuel platform substrate. A six-membered par-substituent with Lewis acid ionic solution was first created by the Diels Alder react. Ring intermediate-4-methyl-3-cyclohexene formaldehyde. Subsequently, under the effect of tungsten carbide catalyst, this intermediate produced PX through continuous gas-phase dehydrogenation-hydrodeoxygenation reaction. As high as 90% was the total PX yield in this two-step process. You can make other bio-based aromatic carbons by changing their substrate molecular substitutions and functional group. The single product yield is 80%-92%.

As a catalyst, the research team employed tungsten carbide powder to produce a highly-coupled reaction between dehydroaromatization as well as hydrodeoxygenation via intramolecular water transfer. The surface shear mechanism of tungsten-carbide reaction in this process is totally different from traditional precious metal catalysis. This means that carbon atoms may be kept in the product at 100%. Water, the principal byproduct of this process, facilitates separation of the PX-product. This research provides a fresh idea to explore the potential for the production of aromatic chemicals with biomass.

In addition, when we think about tungsten, the first thing that pops into our minds is the filament. Tungsten is an uncommon high-melting alloy and has the highest melting point of any unalloyed metallic. Both tungsten and aluminum have extreme electrical conductivity. Edison was a great inventor who used tungsten for making filament. Tungsten has a wide range of applications in modern technology, both in its pure metal state as well as in the alloy system state. It's also called an "industrial tooth" as well as an "industrial salt". This is a strategic essential metal. Current consumption shows that tungsten ore can only be used for approximately 140 years. Recycling tungsten could make up any shortfalls in storage of tungsten.

There are many economic and environmental advantages to recycling tungsten. It has a greater tungsten percentage than the original tungsten, particularly sintered, which can have a higher tungsten level than 90%. Extracting tungsten from tungsten carbonide and other tungsten scraps is a cheaper way to extract tungsten than by using hydrochloric acids. It also results in fewer wastewater emissions, which can reduce the cost of production and help avoid environmental pollution.

What is Tantalum-Carbide? Tantalum Carbide (TaC) are binary compounds that consist of Tantalum or carbon. Their empirical formula is TaCX. X can vary in an arbitrary range from 0.4 to 1 They are extremely tough, hardy, and fragile refractory ceramic materials that can be metal-conductive. They come as a brownish-gray powder, and they are often sintered.
Tantalum Carbide can be used as a cermet and commercially for cutting tools. Sometimes, it is added to the tungsten Carbide alloys.
Tantalum-Carbide ceramics are ceramics that contain seven crystal phases of TantalumCarbide. TaC stands for face-centered cubular lattice. Based on purity and measurements, the theoretical density was 1.44. This number is among the most high-ranking binary compounds. This value is the highest among binary compounds. Hafnium Carbide has an approximately 3942 degree C melting point. While hafnium Carbaide's melting point is similar to TaC, it has a somewhat higher melting point.

TaCX Powders are made from the components by heating mixtures of graphite and tantalum in vacuum or under an inert gas atmosphere such as argon. An arc melting or furnace heats the mixture to around 2000degC. You can also reduce tantalum Pentoxide by adding carbon to it in either a vacuum or hydrogen atmosphere between 1500-1500C. Tantalum Carbide was prepared using this method in 1876. Due to the lack of stoichiometric monitoring, the product could be produced directly from the elements via self-spreading hightemperature synthesis.
A complex combination of ions and metals makes it possible to bond tantalum with the carbon atoms within carbides. Due to their covalent structure, carbides are extremely hard and brittle. TaCX, for example, has a microhardness range of 160 to 2000 kg/mm2[16] (9mohs), and an elastic modulus between 285 GPa and 285 GPa. Tantalum, on the other hand, is 110 kg/mm2 [186 GPa], while these values are 110 and 186 GPa respectively.
Tantalum Carbide is electrically conductive to metals, both size and temperature-dependent.TaC is a kind of superconductor with high transition temperature Tc = 10.35 K.

Is tantalum carbide as strong?
Tests of Vickers hardness, fracture toughness and relative density were done on a variety of samples. It was found that TaC has excellent mechanical properties, with a melting point of 5.5 GPa. TaC has a relative density of 7.4 MPa m1/2 as well as Vickers hardness at 97.7%.

For what purpose is tantalum-carbide used?
Tantalum Carbide is chemically stable, and it was not soluble in acids. The antioxidant properties of Tantalum Carbide are strong. They were usually prepared from tantalum pentoxide in an inert atmosphere or reductive atmosphere. By hot pressing, sintering is possible to produce high-density products and metallic luster. They are used in aerospace and cement carbide additives. Tantalum Carbide, a metallic white cubic crystal powder of the sodium-chloride type cubic crystals system is light brown. It is insoluble and insoluble with water. However, it can be dissolved in hydrofluoric and nitric acids. It can be easily melted to decompose by potassiumpyrosulfate and has a strong resistance against oxidation. It has high electrical conductivity and a large resistance at room temperatures of 30O.
Where is tantalum caride useful? Due to its outstanding physical properties (melting point, hardness. elastic modulus and thermal shock resistance), tantalum caride is often used in a variety of applications, including as a sintering agent in ultra high temperature ceramics (UHTCs).
Tantalum carbide is an additive in powder metallurgy. Titanium Carbide can be worn as an ornament on watches because of its sintered body. Tantalum Carbide is also an inhibitor for grain growth in sintered Cemented Carbide. It has a density 14.1g/cm3.

Is tantalum carbide toxic?
Tantalum Compounds - The systemic toxicity of tantalum dioxide and metallic tantalum are low. Its solubility is probably the reason. Carbides - Pure carbon can be safely handled, and even consumed in the form graphite or charcoal.

Poseidon is a deep, unmanned submersible
2016: A London team discovered Tantalum Carbide or TaC and hafnium Carbide (HfC), which are ceramic materials with the highest melting point known, can be withstand temperatures up to 4,000°C.
Tantrum Carbide as well as hafnium Carbide have a higher resistance to heat than other known materials. They shield a spacecraft against the heat from exit or reentry.
Omar Sediroth Baraza (researcher) stated that spacecraft’s nose caps and scientific equipment need high-temperature resistance materials. Tantalum Carbide and hafnium Carbide may be useful for supersonic future missions.
