  •  Fused Aluminum Oxide Synonyms:

Al2O3, fused aluminum oxide powder, white corundum, white aluminum oxide powder, pink aluminum oxide powder, brown aluminum oxide powder, alumina, corundum, sapphire, ruby, aloxite, CAS# 1344-28-1

  • Fused Aluminum Oxide Designations:

Chemical Name: Aluminum oxide

Chemical Formula: Al2O3

  • Fused Aluminum Oxide Description:  

a) Alumina produced by heating a mixture of calcined bauxite or a relatively pure grade of Al2O3 with iron borings to temperatures above 1980 deg. C in an electric arc furnace; grains of increased toughness may be obtained by the addition of TiO2.

b) Aluminium oxide is an amphoteric oxide of aluminium with the chemical formula Al2O3. It is also commonly referred to as alumina, corundum, sapphire, ruby or aloxite in the mining, ceramic and materials science communities. It is produced by the Bayer process from bauxite.
