Introduction to AlN Powder Aluminum Nitride Aluminum nitride is a covalent bonds compound. The chemical formula for AIN is It is an atomic nitride. The hexagonal, atom crystal of the nitride family, it has a wurtzite-type crystal structure.
Aluminum nitride This synthetic mineral isn’t found in nature. AlN’s crystal structure is hexagonal, a type of wurtzite, having a low density (3.2g/cm3) and high strength. Decomposition takes place at approximately 3060. It also has high thermal conductivity, corrosion resistance and other benefits.

Aluminium Nitride Powder AlN Powder – Physical Properties
AlN stays stable above 2200. At room temperature, AlN has a high strength and decreases in strength with temperature. AlN’s thermal conductivity is high and it also has a low thermal extension coefficient. This makes it a great heat shock material. AlN is a great crucible material to melt and cast pure iron, aluminum or an alloy of aluminum. Aluminium nitride has excellent electrical insulation properties. Aluminum nitride is also an attractive electrical component. It is protected by ion implantation through annealing thanks to the aluminum nitride coat on gallium arsenide. Aluminium nitride also acts as a catalyst in the conversion of hexagonal to cubic boron nutride.
It is slow to react with water at room temperatures. The aluminum powder can be made from ammonia or nitrogen, 800-1000. This product can be described as a grayish-blue to white powder. Gray powder can be obtained by using the al2O3Cā€“N2 system reaction synthesizer at 16001750. You can also use aluminum chloride as ammonia gas. By vapor deposition, the AlCl3/NH3 system can be used to synthesize the coating.

En summa:
1. A high level of thermal conductivity (around 320W/m*K), that is very close to SiC or BeO, and more than 5x higher than Al2O3
2. Excellent electrical properties (eg, dielectric constant, dielectric loss, body resistivity, dielectric strength);
3. High mechanical property. This ceramic has a higher flexural strength than Al2O3 or BeO ceramics and is easily atmospherically sintered.
4. High optical transmission qualities
5. Non-toxic.

Aluminum Nitride AlN Powder – Applications
AlN has piezoelectric characteristics, so the extensional extension properties of AlN are also used in surface Acoustic Wave Detectors. They will be located on silicon wafers.
Aluminum nitride ceramics These materials have high room temperatures and high temperature resistance. They also have a low coefficient of expansion.
Due to their high corrosion resistance, Al nitride Ceramics can be used for casting mold material or crucibles in Al, Cu and Ag melting, as well as other metals.
Aluminum nitride ceramics High-tech ceramics are a brand new type. It has high thermal conductivity, is non-toxic and resistant to corrosion, can withstand high temperatures, thermochemical stability and other characteristics. This substrate makes a good packaging material and heat dissipation medium, as well as circuit components and interconnect carrier for large-scale, integrated circuits. This additive is the most effective to increase the thermal conductivity, mechanical properties, and durability of polymer material. Aluminum nitride can also be used in smelting nonferrous metal and semiconductor galium arsenide. Aluminum nitride has excellent dielectric properties and is an electric insulator. Aluminum nitride protects gallium arsenide from ion implantation in annealing.
