Silicon carbide is composed of light elements, silicon (Si) and carbon (C). Its basic building block is a crystal of four carbon atoms forming a tetrahedron, covalently bonded to a single silicon atom at the center. So silicon carbide has a High hardness, Mohs hardness rating of 9, making it the hardest available material next to boron carbide (9.5) and diamond (10). This apparent property makes SiC an excellent material choice for mechanical seals, bearings, and cutting tools, especially the grinding wheel.
