Brown fused alumina, also known as corundum, is a brown artificial corundum produced by melting and reducing bauxite, carbon-based materials, and iron shavings in an electric arc furnace. Hence, it is named as such. The main chemical component of brown fused alumina is AL2O3, with a content ranging from 95.00% to 97.00%, and it also contains trace amounts of Fe, Si, Ti, etc. Brown fused alumina is a basic abrasive due to its good grinding properties, wide application range, and low cost, making it widely used.
