Introduction to White Corundum
White corundum, also known as white fused alumina, is a high - quality abrasive material. It is produced by smelting industrial alumina powder in an electric arc furnace at high temperatures. With a high hardness (second only to diamond), good self - sharpening property, high purity, and strong cutting ability, white corundum is widely used in various industries. In the abrasive industry, it is used to make grinding wheels, sandpaper, and abrasive belts for precision grinding of various metal and non - metal materials. In the refractory industry, it can be used to produce high - grade refractory products due to its excellent high - temperature resistance. It is also used in the aerospace, electronics, and other high - tech fields for surface treatment and polishing.
