Product Description

ZHENGZHOU LION ABRASIVES CO.,LTD in CHINA

We produce white aluminium oxide FEPA, JIS, GB grit for making abrasive and refractory with purity AL2O3:99.7%Min, it 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.
