Silicon Carbide - Structure, Properties, and Uses of SiC

Silicon carbide crystallizes in a close packed structure covalently bonded to each other. The atoms are arranged so that two primary coordination tetrahedral where four carbon and four silicon atoms are bonded to a central Si and C atoms are formed. These tetrahedra are linked together through their corners and stacked to form polar structures.
