Introduction to White Corundum
White corundum, also known as white fused alumina, is a high - quality abrasive and refractory material. It is produced by melting high - purity alumina powder in an electric arc furnace at extremely high temperatures and then cooling it rapidly. The main chemical component of white corundum is aluminum oxide (Al₂O₃), with a content usually above 99%.
White corundum has excellent physical and chemical properties. It has high hardness, second only to diamond, which makes it suitable for use in abrasive tools for grinding and cutting hard materials such as high - speed steel, alloy steel, and stainless steel. It also has good heat resistance, chemical stability, and low coefficient of thermal expansion, which enables it to maintain its performance in high - temperature and harsh chemical environments. Therefore, white corundum is widely used in various industries, including abrasives, refractories, ceramics, electronics, and aerospace.
