Wfa/white Fused Aluminium Oxide For Abrasives(al2o3 99%min)

1.Description
White Aluminium 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.
