white fused alumina

White Fused Alumina was made from the high qualityalumina by melting above 2000 in the electric arc furnace andcooling. It is white with the main crystal phase alpha-Al2O3.Thewhite alumina produced in titling electric arc furnace has theadvantage of high bulk density and low porosity and the volumestability and thermal shock resistance can beimproved.
