Aluminum nitride, which is a covalent bond compound, has the chemical formula AIN, and is an atomic crystal. Aluminum nitride belongs to diamond-like nitride, hexagonal crystal system, wurtzite crystal structure, it is non-toxic, it is white or off-white powder.

Aluminum Nitride Powder Properties

Aluminum nitride (AlN) has the characteristics of high strength, high volume resistivity, high insulation withstand voltage, thermal expansion coefficient, and good matching with silicon. It is not only used as a sintering aid or reinforcing phase of structural ceramics, especially in recent years. In the field of ceramic electronic substrates and packaging materials, its performance far exceeds that of alumina.

Aluminum nitride has good thermal conductivity and small thermal expansion coefficient, making it a good thermal shock material. Aluminum nitride has strong resistance to molten metal corrosion and is an ideal crucible material for melting and casting pure iron, aluminum or aluminum alloy. Aluminum nitride is also an electrical insulator with good dielectric properties, and it is also promising as an electrical component.

 


Aluminum Nitride Powder Applications

1. Aluminum nitride powder has high purity, small particle size and high activity. It is the main raw material for manufacturing high thermal conductivity aluminum nitride ceramic substrates.

2. Aluminum nitride ceramic substrate has high thermal conductivity, low expansion coefficient, high strength, high temperature resistance, chemical corrosion resistance, high resistivity, and low dielectric loss. It is an ideal large-scale integrated circuit heat dissipation substrate and packaging material.

3.Aluminum nitride has high hardness, which is higher than that of traditional alumina.It is a new type of wear-resistant ceramic material.

4. Utilizing the heat resistance, melt erosion resistance and thermal shock resistance of AIN ceramics, GaAs crystal crucibles, magnetic fluid power generation devices and high-temperature turbine corrosion-resistant parts can be made, and the optical properties of aluminum nitride can be used as infrared windows.

5. Aluminum nitride film can be made into high-frequency piezoelectric components, super-large-scale integrated circuit substrates, etc.

6. Aluminum nitride is heat-resistant, resistant to corrosion by molten metal, stable to acid, but easily corroded in alkaline solution. The new surface of AIN will react when exposed to humid air to form a very thin oxide film. AIN ceramics have good metallization properties and can replace toxic beryllium oxide ceramics and are widely used in the electronics industry.
