What crystal structure is aluminum nitride?
What is Aluminum nitride?
Aluminum nitride (AlN) is a synthetic mineral that does not exist naturally in nature. The crystal structure of AlN is hexagonal wurtzite type, which has the advantages of low density (3.26g/cm3), high strength, good heat resistance (decomposition at about 3060℃), high thermal conductivity, and corrosion resistance.

Toxicity of aluminum nitride
1.On the skin: Causing corrosive effects. Irritate skin and mucous membranes.
2.On the eyes: strong corrosive effects. Stimulating effect.
Preparation method of Aluminum nitride powder
It reacts slowly with water at room temperature. It can be synthesized from aluminum powder at 800~1000℃ in an ammonia or nitrogen atmosphere. The product is white to gray powder blue. Or synthesized by reaction of Al2O3-C-N2 system at 1600~1750℃, and the product is an off-white powder. Or aluminum chloride and ammonia react in the gas phase. The coating can be synthesized by vapor deposition from the AlCl3-NH3 system.

Performance characteristics of Aluminum nitride powder
1.AlN can be stabilized up to 2200℃. The strength is high at room temperature, and the strength decreases slowly with the increase in temperature.
2.Good thermal conductivity, a small thermal expansion coefficient, and is a good thermal shock-resistant material. With strong resistance to molten metal erosion, it is an ideal crucible material for melting and casting pure iron, aluminum, or aluminum alloy.
3.Aluminum nitride is also an electrical insulator with good dielectric properties, and it is also promising to be used as an electrical component. The aluminum nitride coating on the surface of gallium arsenide can protect it from ion implantation during annealing.
4.It is also a catalyst for converting aluminum nitride from hexagonal boron nitride to cubic boron nitride.
5.The relative density is 3. 26; Mohs hardness is 9; the Thermal expansion coefficient is 4. 84× 10-6 K-1 (25 ~ 600℃); Thermal conductivity of 30. IW/(m.k) (200℃); The resistivity is 2× iolln,-cm (25℃); The dielectric constant is 8.15.
