White corundum _ white corundum powder

[Product Specifications]: Various specifications of white corundum fine powder, fine powder, section sand, granular sand

[Production capacity]: 50,000 tons / year

[Scope of application]: Widely used in refractory materials, consolidated abrasives, coated abrasives, precision casting, casting coatings, various high-end products, craftsmanship or hardware and other products to beautify the surface. It is also suitable for refractory bricks, castables, Nozzle skateboard, etc.

【product description】:

White corundum and white corundum powder are made of high-quality alumina powder and refined by electrofusion. They have high purity, good self-sharpness, resistance to acid and alkali corrosion, high temperature resistance and stable thermal properties. Its hardness is slightly higher than that of brown alumina. , Toughness is slightly lower, high purity, good self-sharpness, strong grinding ability, small heat generation, high efficiency, resistance to acid and alkali corrosion, high temperature and thermal stability. It is used to make abrasive tools, suitable for grinding high-carbon copper and high-speed steel. White corundum powder is widely used, such as atomizing and aesthetic processing of Polly or acrylic art products, sand blasting in TV screen manufacturing, advanced refractory materials and other ceramic additives.
