Wholesale White Corundum Powder 70#
Introduction white corundum:
White corundum was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.After two crushing and shaping by the grinder, the iron is magnetically selected and finally sieved into different models of grains. The main chemical component of white corundumgrains is AL2O3, which is white opaque and has a high Mohs hardness. The white corundumgrains has the characteristics of high temperature resistance, acid and alkali corrosion resistance, strong grinding ability and stable thermal performance. It is suitable for surface beautification of glass and metal, and can also be used as raw material for sandblasting and rust removal.
