Silicon Carbide - an overview | ScienceDirect Topics

Silicon carbide (SiC) or carborundum is a synthetic abrasive manufactured through the fusion of high-grade silica sand and finely ground carbon (petroleum coke) in an electric furnace at high temperature (1600–2500°C). The process generates both particles and fibers of silicon carbide as well as quartz and cristobalite silica, all of which may become airborne in the workplace during manufacture.
