White fused alumina
White Corundum is based on high quality aluminum oxide powder as raw material, formed by the crystallization of fused refining, high purity, self-sharpening, good acid and alkali corrosion, high temperature thermal stability performance, it is slightly higher than the brown corundum hardness,
toughness is slightly lower, high purity , self sharpening good grinding
ability, heat a small, high efficiency, acid and alkali corrosion, high temperature thermal stability .
Application:
1.For precision casting and high-grade refractory.
2.For bake lining ,Catalyst carrier ,friction products
3.For pressure blasting hard abrasives;Refractory industry
4.For wet and dry blasting ,grinding,lapping and polishing media
5.For abrasive tools: grinding wheel, Lapping and polishing non-skid title;
6.For bonded and Coated abrasives ,Thermal Spraying (Plasma Spraying)
7.For lapping & Micro-Blasting applications .refractories,Ceramics and Tiles .
