Alumina is a white crystalline powder produced by calcination of aluminium hydroxide.
As the calcination temperature increases,it transforms through ansitional crystal　structure until reaching　α( alpha )-alumina. α-alumina is extremely stable chemically,　with a high melting temperature. It exhibits superior mechanical strength and extreme 
hardness as well as high electrical insulation and high thermal conductivity properties.
