Characteristics:
Aluminum nitride has a hexagonal crystal structure and is a covalent bonded material., and is a kind of white or gray powder of loose.
Aluminum Nitride (AlN) is a ceramic material possessing outstanding properties such as high thermal conductivity, low electrical resistivity, Low thermal expansion coefficient close to that of Silicon, Non-reactive with normal semiconductor process chemicals and gases and high hardness. The material is stable to very high temperatures in inert atmospheres.
Application:
High thermally conductive ceramics, translucent ceramics, Si-Al-O-N compounds, high temperature materials, additives, heat sinks, power and multichip modules, refractories, ceramic armor, break rings, coatings, insulators, heat radiation plates, optoelectronic devices, metal matrix composites, thermally conductive filler, IC packages and substrates, Molten metal handling components, Semiconductor processing chamber fixtures and insulators, Power transistor bases,
