White fused alumina

It is white color with the main crystal phase alpha-Al2O3.The white alumina produced in

titling electric arc furnace has the advantage of high bulk density and low porosity and the

volume stability and thermal shock resistance can be improved. 

Application:

It is used for making bonded and coated abrasive such as grinding wheels, abrasive stones, cutting discs and refractories. It is also widely used for sandblasing and polishing.
