Silicon Carbide (SiC) Properties and …

The basic Silicon carbide structural unit is a covalently bonded major co-ordinated tetrahedron, either CSi4 or Silicon carbide4. The four bonds attached to the neighboring bonds have an entirely covalent character. This bond creates a difference in electronegativity of the carbon and silicon atom. The

Polymorphs of silicon carbide - Wikipedia

16.06.2009· Many compound materials exhibit polymorphism, that is they can exist in different structures called polymorphs. Silicon carbide (SiC) is unique in this regard as more than 250 polymorphs of silicon carbide had been identified by 2006, with some of them having a lattice constant as long as 301.5 nm, about one thousand times the usual SiC lattice spacings.
