White fused alumina for refractory
1.Description
White fused alumina electrically fused in arc furnace with high grade processed alumina as raw material.

It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening,better cutting,less heat emit, higher efficiency,acid and alkali resistance,good thermal stability . It's the high grade refractory materials.
As the abrasive materials , it is suitable for grinding high-speed , high carbon steel , as loose grains , it widely used for bonded and coated abrasive , polishing , precision casting and so on .
