Aluminum oxide, commonly known as alumina, is a versatile and hard-wearing ceramic material that consists of aluminum and oxygen atoms. It exhibits exceptional hardness and is used in a wide array of applications, including as an abrasive material in sandpapers and grinding wheels due to its ability to cut and shape various surfaces. Additionally, aluminum oxide serves as an insulating material in electronics, a catalyst in chemical processes, and as a refractory material in high-temperature environments such as furnaces and crucibles. Its combination of hardness, high melting point, and electrical insulating properties makes aluminum oxide a crucial material in industries ranging from manufacturing to electronics.

Function characteristics of white fused alumina sand: It will not affect the color of the workpiece; It can be used for sand blasting in the process of prohibiting iron powder residue; micro powder grade is very suitable for wet sand blasting and polishing; high processing speed and good quality; the content of iron oxide is very low, which is suitable for sand blasting operation in which iron slag is strictly prohibited; Remove impurities by pickling. White corundum abrasive treatment Many advantages of white fused alumina abrasive contribute to its important application in industry, but the waste of white corundum abrasive used in workpiece processing has become the main problem faced by enterprises. When white fused alumina abrasive is used, abrasive precipitation will occur. Of course, there will be other sundries on the workpiece. If the two are combined, the difficulty of cleaning will be further increased.
