　　Nowadays, synthetic corundum is being used more and more in our daily lives. Examples include brown corundum, white corundum, electrically fused white corundum, and black corundum. Although they are all abrasives, do people know the characteristics of these abrasives? Let the editors from Qianjiaxin Refractories give you a detailed introduction!
The production process of white corundum
White corundum is made by using industrial alumina powder as raw material, melting it in an electric arc at temperatures above 2000 degrees, and then cooling it to produce white corundum. The resulting material is then crushed into desired shapes, iron is removed through magnetic separation, and it is sieved to obtain particles of various sizes. White corundum has a dense structure, high hardness, and well-defined edges and corners. 　　Important physical properties of white corundum: White corundum has good thermal stability, with a tolerance to high temperatures above 1750 degrees. It features high purity, good self-sharpening ability, strong grinding capacity, low heat value, high efficiency, resistance to acids and alkalis; however, its toughness is slightly low. 　　What are the industrial uses of white corundum? 1. It can be used as wet sand, dry sand, or jet sand, as well as for fixing grinding tools and coated grinding tools. 2. It is also important in the ultra-fine grinding and polishing processes in the crystal and electronics industries, as well as in the production of high-quality refractory materials. 3. It can be used as a contact medium, insulator, and in precision casting sands. 4. It is suitable for processing hardening steel, alloy steel, high-speed steel, high-carbon steel, and other materials with high hardness and tensile strength. 　　That’s all for the detailed explanation provided by Xiao Qian on the \"uses and production processes of white corundum abrasives\". Everyone can choose the appropriate white corundum material based on their own specific circumstances!
