5 - 8mm Fine Grit Aluminum Oxide
WHITE ALUMINUM OXIDE FOR REFRACTORY
White fused aluminum oxide is a very high purity oxide, and thus recommended when contamination is an issue to be considered. It is obtained from the fusion of high purity calcined alumina in electric arc furnaces. The result is a product with high hardness, high friability, high purity, high melting point, and large crystal size.
The fused white aluminum oxide 0-1MM, 1-3MM, 3-5MM, 5-8MM, 200MESH, 325MESH, are the main raw material for the production of high-grade indefinite and shaped refractory materials.
