Brief introduction of White aluminum oxide

 

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.
