White fused alumina powder F400 for bonded abrasive or grinding paste

White corundum(WA) is manufactured from Aluminia powder by crystal electro-fusion process at high termperature of over 2000C.Its hardness is a little higher and toughness is a little lower than brown corundum.It has the advantages of high purity, good sharpness, strong grinding force, less calorific value, high efficiency, good acid/alkaline corrosion resistance,high temperature resistance, good thermal stability, etc.

characteristic

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 selected 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.
