Overview of Silicon Carbide - Glenn K. Lockwood
Silicon carbide, due to the close proximity of silicon and carbide on the periodic table, is a highly covalent material that forms tetrahedra that are centered around either carbon or silicon atoms. These tetrahedra form a close-packed structure with half of the tetrahedral sites filled, and occur primarily in the α-SiC and β-SiC phases.
