High Purity White Fused Alumina

White corundum is a white abrasive made from industrial alumina powder (Al2O3) . It is a white abrasive which is melted at high temperature. Its hardness is slightly higher than that of brown corundum and its toughness is slightly lower. It is made by smelting and cooling above 2000 degrees in arc, grinding and shaping, removing iron by magnetic separation, and sieving into many kinds of granularity. It is compact in texture, high in hardness and sharp in shape. It is suitable for making ceramics, resin-bonded abrasives, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc. Manufacture of high-grade refractories, code name "WA" in the international common standards, national standards consistent, most for export, but also a certain amount of supply to domestic users.

High Purity White Fused Alumina
The prominent feature is that the crystal size is small and impact-resistant, if the grinding machine is used to break, the particles are mostly spherical particles, the surface is clean and easy to bindThe abrasive tools made of white corundum are suitable for grinding high carbon steel, plateau steel, high speed steel and quenched steel with harder and stronger tensile strength. It is suitable for solid structure and coated abrasive tools, wet or dry jet sand, ultra-fine grinding and polishing suitable for crystal and electronic industries and making high-grade refractories.
It can also be used as grinding and polishing materials, precision casting sand, spraying materials, chemical catalyst carrier, special ceramics, advanced refractories, etc.
