Fused white corundum alumina powder for refractory

Fused white corundum alumina powder for refractory

[Product Specifications]: 0-1mm1-3mm 3-5mm                                                325mesh 200-0 100-0

[Product performance]: white, more corundum hard, strong cutting force, chemical stability, and has a good insulation.Particle distribution even, no large particles.

White corundum is a high-quality aluminum oxide powder as raw material, made by the crystallization of fused, high purity, self-sharpening, acid and alkali corrosion, high temperature, thermal performance and stability is slightly higher than the hardness of corundum, toughness slightly lower , High purity, good self-sharpening, grinding ability, heat a small, high efficiency, acid and alkali corrosion, high temperature thermal stability. Made of abrasive, suitable for grinding high-carbon steel, high-speed steel and stainless steel and other fine-grained abrasive can also be used for precision casting and advanced refractory materials.

[Application]: can do solid and coated abrasive, wet or dry or jet sand, suitable for crystal, the electronics industry, ultra-fine grinding and polishing and making high-level refractory materials. Raw materials for polishing wax and Whetstone. Can also be used as touch media, insulators and precision casting sand.
