Introduction to White Corundum
White corundum, also known as white fused alumina, is a high – quality abrasive and refractory material. It is produced by fusing high – purity alumina powder in an electric arc furnace at extremely high temperatures. The resulting product has excellent properties such as high hardness, good thermal stability, high chemical purity, and strong abrasion resistance. White corundum is widely used in various industries, including abrasives (such as grinding wheels, sandpapers), refractory materials (for lining furnaces), and high – precision surface finishing applications.
