Aluminum nitride , a covalent compound with the chemical formula AIN is an atomic-crystal. Aluminum nitride has a hexagonal system of crystals, wurtzite, and is a non-toxic powder.

Aluminum Nitride Powder Properties

Aluminum nitride, or AlN, has many characteristics, including high strength, volume resistivity, insulation withstand voltage and thermal expansion coefficient. Recently, it is used not just as a reinforcing phase or sintering agent for structural ceramics. In ceramic electronic substrates, and packaging materials its performance is superior to that of alumina.
Aluminum nitride, with its high thermal conductivity and low thermal expansion coefficient is an excellent thermal shock material. Aluminum nitride resists corrosion when molten and is a good crucible material to melt and cast pure iron, aluminum and aluminum alloys. Aluminum nitride also has excellent dielectric properties. It is also a promising material for electrical components.


Aluminum Nitride powder Applications

1. Aluminum nitride has a high purity, small particle sizes and high activity. Aluminum nitride is the main raw materials for high thermal conductivity aluminum-nitride ceramic substrates.

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.

The hardness of aluminum nitride is much higher than traditional alumina.

4. Using AIN ceramics’ heat resistance, melting erosion resistance and thermal-shock resistance, GaAs crucibles, magnetic-fluid power generation devices, high-temperature turbine-corrosion-resistant components can be made. The optical properties of aluminum nitride are also useful as infrared-resistant windows.

5. Aluminum nitride can be used as a substrate for super-large-scale integrated electronic circuits, high-frequency components, etc.

6. Aluminum nitride resists heat, is resistant against corrosion caused by molten steel, is stable with acid but easily corroded when in an alkaline solution. When exposed to humidity, the new surface will form a very fine oxide film. AIN ceramics can be used to replace beryllium-oxide ceramics, which are toxic. They are also widely used in electronics.
