Al2O3, Fused aluminum oxide, White corundum, White aluminum oxide, Pink aluminum oxide, Brown aluminum oxide

Chemical Name: Aluminum oxide

Chemical Formula: Al2O3

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.

Purities are available from as high of a typical purity of 99.999% down to 90+%.

Numerous grit / mesh / micron particle size options are available from READE as large as a nominal sized 50 mm tumbling media down to as small as nano particles sized 20-100 nanometers.
