Aluminum nitride Aluminum nitride belongs to diamond-like nitride. It has a hexagonal crystal system and wurtzite structure. Aluminum nitride has a hexagonal system of crystals, wurtzite. It’s non-toxic and is available as a white or off-white dust.

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. Its performance in ceramic electronic substrates, packaging materials and other fields 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 alloy. 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, a small particle size, and possesses a high activity. It 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 the ideal material for packaging and heat dissipation of large-scale integrated systems.

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

4. Using the heat resistance, melting erosion resistance, and thermal shock resistant of AIN Ceramics, GaAs Crystal Crucibles, magnetic liquid power generation devices, high-temperature turbines corrosion-resistant components can be made. The optical properties of Aluminum Nitride can also be used as an infrared window.

5. Aluminum nitride can be used as a substrate for super-large 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. The new surface will react with humid air and form a very fine oxide film. AIN ceramics can be used to replace toxic ceramics made of beryllium and they are commonly used in electronics.
