Black silicon carbide is well noted as one of nice artificial material , also named emery grain or carborundum , which is produced by high-temperature smelting of electric furnaces such as quartz sand, petroleum coke (or blind coal), and wood chips, it can be called gold steel sand or refractory sand. hexagonal crystals, specific gravity of 3.20 ~ 3.25, microhardness of 2840 ~ 3320kg / mm2.
Solar wafer, semiconductor wafer and quartz chip wire sawing and lapping, bonded and coated abrasive tools: stone polishing; processing metal and non-ferrous metal with low tensile strength, such as: gray pig iron, brass, aluminum, stone, leather and rubber.
