1.white 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 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.
