What material is brown corundum?

Brown corundum, commonly known as emery, is smelted from bauxite, iron filings and anthracite in an electric arc furnace. It has high hardness and wear resistance, as well as certain toughness and impact resistance. Because of its brown color, it is called brown corundum.

Brown corundum is widely used in abrasive materials, refractory materials, ceramic materials and other fields. In terms of abrasive materials, brown corundum is used to make abrasive tools, grinding wheels and sandpaper, etc., and has good effects on grinding and polishing various materials. In terms of refractory materials, brown corundum bricks are an important building structural material with excellent fire resistance and mechanical strength. They are widely used in metallurgy, chemical industry, electric power and other industries. In terms of ceramic materials, brown corundum is also used to make various ceramic products, such as ceramic knives, ceramic bearings and ceramic pipes.

In short, brown corundum is a man-made material with a wide range of applications. It has relatively high hardness and wear resistance, and also has certain toughness and impact resistance. It has good application prospects in the fields of abrasive materials, refractory materials and ceramic materials.
