Green silicon carbide (SiC) is a synthetic, ultra-hard abrasive material produced in an electric resistance furnace at high temperatures using a mixture of quartz sand, petroleum coke, and common salt, with added silica and carbon for purity control. Its distinctive green color comes from its high purity, typically containing over 99% silicon carbide crystals, with minimal metallic impurities compared to its black counterpart. This results in superior hardness, brittleness, and sharpness, making it one of the hardest materials available, second only to diamond and boron carbide.
