WHITE ALUMINUM OXIDE FOR REFRACTORY
White aluminum oxide is a high-grade refractory raw material with white and crystal color . It has the advantages of large bulk density and low porosity, which can effectively improve the volume stability and thermal shock resistance of materials.
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.
