Aluminum Oxide(Al2O3):

Aluminum oxide is made from high quality alumina by melting above 2000° C in the electric arc furnace and then cooling.
Aluminum Oxide is with high purity, great self-sharpening, acid and alkali resistance, high temperature and stable thermal performance.

Alumina Appearance: White powder.
Application: High-pressure sodium lamp tube, the long twilight luminous powder, grinding materials, catalyst carrier, ruby, sapphire.
