Property of aluminum nitride Powder
Aluminum nitride has the chemical formula AlN. It belongs to the hexagonal crystal system and has a wurtzite structure.
Aluminum nitride has a stable temperature up to 2200. It is strong at room temperatures and loses strength slowly as temperature increases. Aluminum nitride is a thermal shock resistant material with good thermal conductivity. AlN Powder is a good crucible material because 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. The Aluminum Nitride Ceramic Substrate has a high thermal conductivity. It is also a material with fewer dielectric losses, good chemical corrosion resistance and high temperature resistance. It is a suitable large-scale heat dissipation and packaging substrate for integrated circuits.
Aluminum nitride has a higher hardness than alumina. However, due to the high price, it is only suitable for parts that are severely worn.
4. AlN ceramics have the ability to resist heat, melt erosion, thermal shock, and can be used in high-temperature turbines and magnetic fluid power generation devices. Its optical properties can also be utilized as an infrared glass. Aluminum nitride can be made 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 to acids, 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, silver, copper, lead, and other metals using this property. AlN ceramics can be used to replace beryllium-oxide ceramics that are toxic and have excellent metallization properties. They are also widely used in electronics.
