Fine Powder White Aluminum Oxide for Refractory Coating


1. Description:

White Aluminum Oxide Abrasives, a kind of high-grade refractories, was made from the imported high quality alumina by melting above 2 000 in the electric arc furnace and cooling.

It is white with the main crystal phase αAl2O3.

The white alumina produced in the 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.
