Description:Black Silicon Carbide is produced in electrical resistance furnaces from high purity
silica sand and petroleum coke. Its combination of being very hard and sharp makes it a very aggressive abrasive ideal for coated abrasive applications.
Application:Coated Abrasive materials can be used for the polishing, finishing or stock removal from wood, metal, ceramics, plastics, rubber, stone and other materials.
