white fused aluminum oxide TDS
White fused alUmINUM OXIDE
White Fused aluminum oxide 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 α-Al2O3.The white alumina 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.
