9.0 Mohs Hardness White Aluminum Oxide F30 Industry Grinding
1. Introduction
White corundum is made from industrial alumina powder, which is melted in arc furnace at a high temperature of more than 2000 degrees and then cooled. After grinding and shaping, magnetic separation of iron, particle size screening into different products. With the close texture, high hardness, angular shape, it is suitable for the manufacture of ceramics, resin consolidation abrasive tools and grinding, polishing, sandblasting, precision casting (investment casting special corundum), and it can also be used for the manufacture of high-grade refractory materials.
