White Fused Aluminum Oxide

White Fused Aluminum Oxide
Description:
White fused 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 characterized by high purity, high hardness, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, and good thermal stability.
Application:

1. Used for making abrasive tools
2. Refractory materials
3. Grinding, lapping, polishing and blasting media
