Property of aluminum nitride Powder

Aluminum nitride has the chemical formula AlN. It belongs to the hexagonal crystal system and wurtzite structure.

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 ideal for casting pure aluminum, iron or alloys of aluminum. It has a high resistance to corrosion from molten metal. Aluminum nitride has good dielectric and electrical properties.

Use of aluminum nitride:

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

1. Aluminum nitride powder AlN has high purity and 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 low expansion coefficients, high strength and resistance to chemical corrosion. It is an excellent large-scale heat dissipation and packaging substrate.

Aluminum nitride has a higher hardness than traditional alumina. However, due to the high price, it can only replace severely worn parts.

4. AlN ceramics have excellent heat resistance, melt erosion resistance, thermal shock resistance, and can be used in the manufacture of GaAs crucibles and Al evaporating dishes. Magnetic fluid power generation devices, high-temperature turbo-corrosion-resistant parts, and their optical properties can be utilized as infrared Windows. Aluminum nitride can be formed into ultra-large-scale integrated-circuit substrates, high-frequency piezoelectric components and other products.

5. Aluminum nitride (AlN) powder is heat resistant, resistant to molten metal corrosion, stable in acid but easily corroded by alkaline solution. 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 toxic ceramics made of beryllium dioxide and have excellent metallization properties. They are also widely used in electronics.
