99.5% Al2O3 white fused alumina refractory
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.
