White fused aluminum/white corundum/WA, a kind of high-grade refractories, 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 α-Al2O3. Its dense texture, high hardness, granular form sharp corners.

  1. High hardness, particle density, good circular single particles.
  2. The pure white color, without impurities, guarantee the wear-resisting layer or wear-resisting paper colour and lustre and transparency.
  3. The particle size distribution uniform concentration, single particle shape, with the least amount of biggest wear-resisting effect.
  4. It is ed commit suicide by hanging oneself more than two thousand degrees high temperature melting of high quality white corundum as raw material, made of fine, white corundum its stable chemical properties do not interact with acid, alkali, with low thermal shrinkage.
