Product Details

high purity white aluminum oxide micropowder in polishing

Introduction white corundum:

White fused alumina 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.

White corundum characteristics:

High purity, good self sharpening, acid and alkali corrosion resistance, high temperature resistance, thermal stability it is slightly higher than the corundum hardness, toughness is a bit low, high purity, good self sharpening, strong grinding ability, low calorific value, high efficiency, acid and alkali corrosion resistance, high temperature stability.
