Products Description
Black silicon carbide powder has a high hardness, with a hardness of 9.2-9.3 on the Mohs scale and a Vickers hardness of 2200, which is higher than corundum and lower than diamond, which makes it have important applications in the abrasive industry. It has good thermal conductivity, is a semiconductor, can resist oxidation at high temperatures, has good thermal shock resistance, small size, light weight and high strength.High purity, less free carbon, iron and other impurities, is conducive to the sintering of silicon carbide ceramics, and improves the purity and quality of ceramic products.
