Black Carborundum (SiC) is an extremely hard (Mohs 9.1/ 2550 Knoop) man made mineral that possesses high thermal conductivity and high strength at elevated temperatures (at 1000°C, SiC is 7.5 times stronger than Al203 ). SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2600°C.
Black Carborundum is a new type of strong composite deoxidizer, which replaces the traditional silicon powder and carbon powder for deoxidation. Compared with the original process, the physical and chemical properties are more stable, the deoxidation effect is better, the deoxidation time is shortened and the slag formation is early. It is of great value to reduce the atmosphere, save energy, improve steel making efficiency, improve quality, reduce the consumption of raw and auxiliary materials, reduce environmental pollution, improve working conditions and improve the comprehensive economic benefits of electric furnaces. In addition, silicon carbide has wide applications in high-grade refractory bricks, nozzles, electronic boards, refractory materials.etc.,
