Property of aluminum nitride Powder

Aluminum nitride has the chemical formula AlN. It belongs to the hexagonal system of crystals, wurtzite structure, and is non-toxic.

Aluminum nitride has a stable temperature up to 2200. It is strong at room temperatures and loses strength slowly with increasing temperature. Aluminum nitride is a thermal shock resistant material with good thermal conductivity. AlN Powder is an ideal crucible to cast pure iron or aluminum alloys. It has a high resistance to molten corrosion. Aluminum nitride has good dielectric and electrical properties.

Use of aluminum nitride:

Aluminum nitride has many uses in optoelectronic engineering. It is used as a dielectric in optical storage interfaces and electronic substrates, as a chip carrier with incredibly high thermal conductivity for military purposes, and also as a chip carrier.

1. Aluminum nitride powder AlN has a high purity, a small particle size, and possesses a high activity. It is used as the main raw material to produce high thermal conductivity aluminium nitride ceramic substrat.

2. Aluminum nitride is a ceramic substrate with high thermal conductivity. It has a low expansion coefficient and high strength. It is a suitable large-scale heat dissipation material and packaging substrate for integrated circuits.

Aluminum nitride has a higher hardness than traditional alumina. However, due to the high price, it is only suitable for parts that are severely worn.

4. AlN ceramics have excellent heat resistance, melt erosion resistance, thermal shock resistance, and can be used in the manufacture of GaAs crystals, Al evaporating plates, magnetic fluid generation devices, high-temperature turbo-corrosion-resistant parts, and their optical properties can be utilized as infrared Windows. Aluminum nitride can be used as a substrate for ultra-large-scale integrated electronic circuits, high-frequency piezoelectric components and other products.

5. Aluminum nitride (AlN) powder is resistant to heat and corrosion, even when molten metal is present. It’s stable to acids, but easily corrodes in alkaline solutions. AlN’s new surface will react with humid air and form a very fine oxide film. It can be used to melt aluminum, copper silver, lead, and other metals using this property. AlN ceramics can be used to replace beryllium-oxide ceramics that are toxic and have excellent metallization properties. They are also widely used in electronics.
