Due to the low natural content, silicon carbide is mostly artificial. The standard method is to mix quartz sand with coke, use the silica and petroleum coke, add salt and wood chips, put it into an electric furnace, heat it to a high temperature of about 2000 °C, and obtain silicon carbide powder after various
