Brown fused alumina is bauxite as the main raw material, adding coke (anthracite), iron and other auxiliary materials, in the arc furnace by high temperature smelting, with high purity, good crystallization, strong liquidity, low linear expansion coefficient, corrosion resistance characteristics. Brown fused alumina is generally brown, composition: AL2O3≥95%; Fe2O3≤0.5%; SiO2≤2.5%; TiO2≤3.3%, Brown fused alumina has the characteristics of no initiation, no pulverization and no cracking in the refractory process. Its cost performance is higher than other traditional corundum materials, become the best metallurgical/refractory aggregate and filling material.Composition content:(%) | AL2O3% | TiO2% | SiO2% | Fe2O3% | L.O.I | Bulk density g/cm3 |
