Sandblasted brown corundum

Brown fused alumina is made of bauxite and coke (anthracite) as the main raw materials, and is smelted at high temperature in an electric arc furnace. The main chemical composition of brown corundum is AL2O3, its content is 94.5%-97%, and it also contains a small amount of Fe, Si, Ti, etc. Brown fused alumina has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient and corrosion resistance.
