Aluminum nitride powder’s property:
Aluminum-nitride has a chemical composition of AlN. This atomic crystal belongs to a diamond-like, hexagonal, crystal system.
Aluminum nitride dust can be stored up to 2220 degrees Celsius. The powder has a high temperature resistance and decreases in strength with increasing temperature. The thermal conductivity of aluminum nitride is high and the thermal expansion coefficient low, which makes it an excellent material for thermal shock. AlN powder resists molten metal corrosion well and makes a great crucible for making aluminum, pure iron or an aluminum alloy. An electrical insulator, aluminum nitride is also available in powder form with excellent dielectric qualities.
Aluminum nitride powder application:
Aluminium nitride can be used for optoelectronics engineering as an optical storage interface dielectric and substrate and as a high-temperature chip carrier. It is also useful in military and other applications.
1. Aluminium nitride alN powder is high in purity and small size. It also has high activity. It’s the principal raw material used to manufacture high thermal conductivity aluminum Nitride ceramic substrates.
2. High thermal conductivity, low expansion factor, high strength and high resistance to chemicals, corrosion resistance, heat resistance, high dielectric loss, and high thermal conductivity make aluminum nitride ceramic substrate a great choice. The ideal material for packaging and heat dissipation in large integrated circuits.
3.Aluminum-nitride powder is hardier than conventional alumina. It can be used only for very damaged parts due to the high price.
4. You can use the thermal resistance and melt erosion resistance of AlN ceramics to create GaAs crystal-crucibles and Al evaporating plates, as well as magnetic fluid power generator devices, high-temperature turbine parts and magneto-power generation devices. Its optical properties are also useful for making infrared window applications. Aluminum nitride can be turned into ultra-large scale integrated circuit substrates or high frequency piezoelectric elements.
5. Aluminum nitride dust is extremely heat resistant, resists corrosion by molten iron, can withstand acid but easy to corrode in an alkaline solution. AlN’s new surface reacts to moisture to create a thin oxide film. It can also be used for casting metals such as aluminum, copper and silver. AlN ceramics can be used to replace toxic beryllium-oxide ceramics. They are also good at metallization.
