Description
High Purity White Fused Alumina/White Corundum from China
Corundum is the most common naturally occurring crystalline form of aluminiumoxide.
white fused alumina is high grade refractory material,which made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.
Size Available:
Abrasives F16-F220, F230-F1200, JIS240-JIS3000
Refractory 0-1mm,1-3mm,3-5mm,200mesh,325mesh
Other special specifications could be supplied as required.
The features of white Corundum
It has higher hardness and slightly lower toughness compared with brown fused alumina. It is also characterized by its high purity, ability of self-sharping , better cutting ,less heat emit ,higher efficiency ,acid and alkali resistance ,good thermal stability.Abrasives tools made of it are suitable for grinding high-speed ,high carbon steel,etc.
It also can be used as material for grinding and polishing ,precision casting ,spaying and coating, medium body for chemical industry ,special ceramics and high-grade refractory materials,etc.
