White fused alumina/Corundum grit 0-1mm for refractory
White fused alumian/corundum is an artificial corundum abrasive, the main component of aluminum oxide (Al2O3), and contains a small amount of iron oxide, silicon oxide, etc., the color was white. White corundum high quality alumina powder as raw material, refined crystalline and fused into, there are dense texture, high hardness, high temperature, acid corrosion, thermal stability properties. particles cusp form for use in the manufacture of ceramics, resin bonded abrasives and grinding, polishing, blasting, precision casting, can also be used to manufacture advanced refractory.
