Aluminum Nitride (AlN) Powder boasts a range of outstanding characteristics, including a thermal expansion coefficient close to that of silicon. Huawei produces top-quality Aluminum Nitride (AlN) Powder at a competitive price, with a standard particle size ranging from 1.0 to 2.0 μm. Customized services are also available to meet specific requirements.
Aluminum nitride, covalent bond compound, chemical formula AIN, atomic crystal, belongs to diamond-like nitride, hexagonal crystal system, wurtzite type crystal structure, non-toxic, white or off-white
Application
1.Because of the piezoelectric properties of al nitride, the extensional extension of al nitride crystals is also used in surface acoustic wave detectors. The detectors are placed on silicon wafers. There are very few places where these thin films can be reliably made.
2.Aluminum nitride ceramics have high room temperature and high temperature strength, small coefficient of expansion, good thermal conductivity, can be used as high temperature structural parts of the heat exchange equipment materials.
3.Aluminum nitride ceramics can be used as crucible and casting mold material for melting of Al, Cu, Ag, Pb and other metals by virtue of its corrosion resistance of iron, aluminum and other metals and alloys.
