Description
Black Silicon Carbide is a highly hard and brittle abrasive that is commonly used in grinding and cutting applications. It is made by heating a mixture of silica sand and petroleum coke in an electric furnace to high temperatures. The resulting product is then crushed and graded to the desired particle size.
Black Silicon Carbide is characterized by its high hardness, low thermal expansion, and resistance to thermal shock. It is also chemically inert, making it suitable for use in harsh environments. Its abrasive properties make it ideal for use in grinding wheels, sandpaper, and other abrasive products.
