White aluminum oxide for abrasives tools and sandblasting

White aluminum oxide was made from the high quality alumina by melting above 2200 in the electric arc furnace and cooling.  

White aluminum oxide is white with the main crystal phase alpha-Al2O3.  

White aluminum oxide 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.
