Black silicon carbide use quartz sand and petroleum coke as the main raw material, smelting the raw material at high temperature electric resistance furnace . Black silicon carbide contains SiC about 95%. The toughness is higher than that of green silicon carbide, black crystals. The microhardness is HV3100-3280kg / mm², brittle and sharp and has a certain electrical conductivity and thermal conductivity. Abrasive made of black silicon carbide is suitable for grinding cast iron, nonferrous metals and rubber, leather, plastic, wood, minerals and other non-metallic materials. Additionally, you can make advanced refractory material and so on.
