Silicon Carbide - an overview | ScienceDirect Topics

R.F. Davis, in Reference Module in Materials Science and Materials Engineering, 2017 Introduction. Silicon carbide (SiC) is a generic name for a material produced by numerous process routes that result in a host of different external and internal microstructures and, as a consequence, a broad range of properties. Within a SiC crystal the Si and C atoms form very strong tetrahedral covalent
