NR0215 Micro Aluminium Nitride (AlN) Powder (CAS No. 24304-00-5)

Micro-Aluminium Nitride (AlN) Powder Description

Micro-Aluminium Nitride (AlN) (CAS: 24304-00-5) is a covalently bonded compound that forms an atomic crystal. It is a synthetic mineral that does not occur in nature. The crystal structure of AlN is of the hexagonal wurtzite type, which exhibits low density, high mechanical strength, stable thermal behaviour, high thermal conductivity and resistance to corrosion.

Aluminium nitride (AlN) is stable up to 2200℃. It has a low coefficient of thermal expansion and withstands temperature shocks. It is employed as a crucible material for casting pure iron, aluminium or aluminium alloys. Aluminium nitride functions as an electrical insulator, exhibits satisfactory dielectric properties and is used in electrical components. It is used as a substrate for integrated high-performance circuits and packaging materials.
