Greenearth - Aluminum Oxide
Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al2O3. Aluminum oxide is a white odorless crystalline powder. Properties (both physical and chemical) vary according to the method of preparation; different methods give different crystalline modifications. The variety formed at very high temperature is quite inert chemically.
