Refractory Brown Fused Alumina/Brown corundum
Introduction of Brown fused alumina / brown corundum
Brown corundum is made of high-quality bauxite as the main raw material. It is smelted into blocks in high temperature furnaces above 2000 degrees, and after crushing and magnetic separation, the particle size models with different compositions are screened. The content of AL2O3 in brown corundum is above 95%, and the hardness is relatively high.Brown fused alumina is used in the electronics industry to increase the adhesion of the surface of the product.
