Silicon Carbide For Sale black silicon carbide green silicon carbide silicon carbide for steelmaking silicon carbide powder / silicon carbide granule Silicon carbide(silicon carbide block), also known as emery or refractory sand, has a chemical formula of SiC and is a very widely used inorganic substance. There are two types of silicon carbide obtained by industrial production, namely black silicon carbide and green silicon carbide. Black Silicon Carbide Black silicon carbide is produced by the reduction reaction of quartz sand and coke powder in a high-temperature environment. Its Mohs hardness is between , and its microhardness is 3300Kg/Cm3. Material characteristics: The content of SiC in black silicon carbide is more than 95%, and its strength and toughness are greater than that of green silicon carbide, but its hardness is lower. Most of it is used to process materials with low tensile strength, such as ground cast iron, non-metallic materials, glass, ceramics, and
