Nano Aluminium Nitride Powder Description
Nano Aluminium Nitride Powder has good thermal conductivity and a small thermal expansion coefficient, so it is a good thermal shock-resistant material. It has a strong ability to resist molten metal erosion and is an ideal crucible material for melting and casting pure iron, aluminum, or aluminum alloy. Aluminum Nitride is also an electrical insulator with good dielectric properties, and it is also promising for use as an electrical component. The Aluminum Nitride coating on the GaAs surface protects it from ion implantation during annealing. Aluminum Nitride is also a catalyst for the transformation from hexagonal boron nitride to cubic boron nitride.
