Overview of Silicon Carbide
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.
Carbide | chemical compound | Britannica
Carbide, any of a class of chemical compounds in which carbon is coined with a metallic or semimetallic element. Calcium carbide is important chiefly as a source of acetylene and other chemicals, whereas the carbides of silicon, tungsten, and several other elements are valued for their physical hardness, strength, and resistance to chemical attack even at very high temperatures.
