 Silicon carbide structure Silicon carbide is a typical covalently bonded stable compound.Theoretically, silicon carbide is made of SiC tetrahedra, but the difference is only parallel or antiparallel bonding. 75 variants of SiC are available, such as α-SiC, β-SiC, 3C-SiC, 4H-SiC, 15R-SiC, etc. All these structures can be divided into square crystal system, hexagonal crystal system […]
