white fused alumina
White Fused
Alumina 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 alpha-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.
