90# grit aluminum oxide white
1.Product Description
grit aluminum oxide white is melting above 2000 in the electric arc furnace and cooling. I
t is white with the main crystal phase alphaAl2O3.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.
