Introduction to White Corundum
White corundum, also known as white fused alumina, is a high - quality abrasive material. It is produced by melting high - purity alumina powder in an electric arc furnace at extremely high temperatures and then cooling it. The main chemical component of white corundum is Al₂O₃, with a content usually above 99%.
White corundum has excellent physical and chemical properties. It has high hardness, second only to diamond, silicon carbide, and boron carbide. This high hardness makes it suitable for a wide range of abrasive applications, such as grinding, polishing, and sandblasting. It also has good chemical stability, being resistant to most acids and alkalis, which allows it to be used in harsh chemical environments. Additionally, white corundum has high refractoriness, enabling it to withstand high temperatures without significant deformation or chemical change. These properties make white corundum widely used in industries such as machinery, metallurgy, electronics, and aerospace.
