Polishing powder fused white alundum

Polishing powder/grinding material fused white alundum 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 Polishing powder/grinding material fused white alundum 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.
