正文 <p id="cs">Brown fused alumina takes the high quality bauxite as the raw material, mixing with iron powder and anthracite, produced by melting in the electric arc furnace at a high temperature over 2000℃. Main chemical compositions are AL2O3, TiO2, and small amount of SiO2 and Fe2O3 etc. Toughness is higher than SiC. The texture is dense, the hardness is high, and the grains appear the spherical shape. It is suitable for manufacturing ceramic and resin high-consolidation abrasive tools, as well as grinding, polishing, sandblasting, precision casting, etc. It can also be used for manufacturing high-grade refractory materials. So the brown fused alumina grain is called as the “Industry Teeth”.</p>
