White fused aluminum oxide is a kind of high-grade refractory and abrasives, was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. The micro hardness of the product is 2200-2300kg/mm2. The abrasive tools made of it are suitable for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as sandblasting, lapping and polishing medium, precision founding sand, coating materials, catalyst carrier, special ceramics and super refractory materials.
▼Performance:
●High hardness, particle density, good single particle roundness;
●White, no impurities, ensuring wear-resistant layer or wear on paper color and transparency;
●Particle size distribution concentrated, single single-particle form, minimum amount with maximum effect
●Selected from the melting temperature by more than 2000 degrees well made of quality industrial alumina as raw material, its chemical stability and acid and alkali effect does not occur, small shrinking
