The chemical formula of calcium nitride is Ca3N2. It is a red-brown crystalline solid compound made up of calcium and nitrogen. It is formed along with the oxide, CaO, when calcium burns in the air.
There are several isomorphs of this material. a-calcium nitride is the most common form.
This isomorphous form of nitride is used to prepare high-end phosphors. It is also used in diamond tools, metal ceramics, and high-temperature alloy additives.
In order to make this isomorphous, it is heated in pure N2 gas flow at 450 for 3 to 4 hours. This temperature is the highest at which calcium nitride can be made. Because of the crystalline transformation of calcium metal at this temperature (hexagonal crystal Ca - body-centered cubic Ca), the lattice structure becomes loose, and nitriding reaction speed is very fast.
When calcium nitride is dissolved in water, it forms calcium hydroxide which releases ammonia. The resulting solution is soluble in dilute acid and decomposes in anhydrous alcohol.
It is an important reagent in the chemical industry. It can be reacted with hydrogen to obtain active nitride ions. It can also be used as a desiccant, reducing agent and chemical analysis reagent. It is suitable for the production of light-emitting diode phosphors and hydrogen fuel cells. It is available in bulk quantity. is a leading supplier and manufacturer of high-quality calcium nitride.

Aluminum carbide, Al4C3, is a complex crystal compound of alternating layers of aluminum and carbon. Each aluminum atom is coordinated to 4 carbon atoms. The alternating tetrahedra of aluminum and carbon atoms form an unusual crystal structure that is stable at temperatures up to 1400 degC.
Metals that form carbides exhibit several unique properties in addition to their toughness. They often possess high refractoriness and low thermal expansion, and are generally highly resistant to corrosion and oxidation. These characteristics make them ideal for coatings used on tools, drills and other industrial materials.
Some of the most common carbide compounds of aluminum include aluminum fluoride (AlF3), sodium aluminate (NaAlH4) and lithium aluminate (LiAlH4). Lithium aluminate is widely used as a reducing agent in organic synthesis and as a stabilizer in electrolytic aluminum production.
It can be produced by reacting the alumina with a halogen. It is inert, subliming without melting at 1291 degC and exhibits a bridge-like structure with good properties for molecular compounds.
Other carbides can be formed by combining aluminum with other elements, such as magnesium, silicon, copper and manganese. The aluminum ions bind to the carbon atoms of other metals, resulting in alloys that are hard, refractory and have low thermal expansion.
Various zeolite materials are being produced using aluminum dross as a raw material. These zeolite materials have been used in applications such as waste treatment, filtration and separation. Some of these materials also have applications in solar cells, biomedical devices and fuel cells.
3d printing inconel 718 is a new technology that allows you to create any product you can imagine. It is a type of additive manufacturing (AM) process that uses CAD data to create a digital representation of a physical part, which is then built by fusing successive layers of powder material using a laser or other light source.
This process allows you to create geometrically complex parts that would otherwise be impossible to manufacture. Moreover, 3d printing is a cost-effective solution because it can construct parts that require minimal material usage and little or no waste.
The first step is to create a CAD model that defines the shape of the product you want to print. Then, a layer of Inconel powder is spread on the printer's bed, and a laser fuses the material. Depending on the machine and the type of powder, this process can produce 16-30 microns of precision at a time.
DMLS is a metal 3D printing technology that uses direct metal laser sintering to make parts solid, without the need for post-processing. It is a very accurate, high-quality and reliable way of producing parts that are not only solid but also have great detail, high layer heights and a smooth finish.
Although Filamet(tm) has some disadvantages compared to DMLS, it is still an excellent choice for a large variety of applications, such as prototyping and casting. It has a high resistance to oxidation and corrosion, good strength, tensile, fatigue and creep-rupture properties, as well as easy fabrication and welding.
