white aluminum oxide crystals for sand blasting

white aluminum oxide crystals for sand blasting was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white aluminum oxide crystals for sand blasting produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
