White Aluminum oxide (White Fused Alumina), is made from the imported high quality alumina by melting above 2000℃ in the electric arc furnace in our plant. It is pure white color with the main crystal phase α-Al2O3. White fused Aluminum oxide produced in the tilting furnace has the advantage of high bulk density and low porosity, thus the volume stability and thermal shock resistance can be improved.
