Nano-Aluminium Nitride Powder Description
Nano-Aluminium Nitride Powder exhibits a thermal conductivity that meets standard engineering requirements and a low coefficient of thermal expansion, thereby withstanding repeated thermal cycles. It resists erosion from molten metal and is employed as a crucible material for melting and casting pure iron, aluminium or aluminium alloys. Aluminium nitride functions as an electrical insulator and fulfils the necessary dielectric criteria for use in electrical components. The aluminium nitride coating on GaAs surfaces is applied to protect against ion implantation during annealing. It is also used as a catalyst in the conversion of hexagonal boron nitride to cubic boron nitride.
