Sell white fused alumina

White aluminum oxide is electrically fused in the arc furnace from high grade bayer processed alumina as raw material, and made into different grain sizes through crashing, magnetic, screening, separating, washing etc. It is characterised by high purity, high hardness, ability of self-sharpening, better cutting, less heat emit, higher efficiency,acid and alkali resistance, and good thermal stability.
