Silicon Oxycarbide - an overview | ScienceDirect Topics
Silicon oxycarbide glasses, or “black glasses”, produced by a sol–gel process from organo trimethoxysilanes, have been characterised by 29 Si MAS NMR (Zhang and Panta990).In these glasses, which have the general formula SiC x O 2(1–x), one tetravalent carbon substitutes for two divalent oxygen atoms, leading in the amorphous network to the formation of C(Si) 4 units; part of the

Is Silicon Carbide a Good Conductor of Electricity
Silicon carbide is an extremely hard bluish-black insoluble crystalline substanceproduced by heating carbon with sand at a high temperature andused as an abrasive and refractory material. There are many appliions of silicon carbide, such as slide bearings, sealing rings, wear parts, sintering aids, crucibles, semiconductor appliions, heating elements, burner nozzles, heat exchangers.

Hot Pressed Silicon Carbide is a high density, high strength material which has been used in refractory appliions for many years. It is now used for a wide range of engineering appliions. Silicon Carbide can be highly polished and has potential for space-based mirrors, because of its high specific strength and stiffness compared with those of glass.
Advanced ceramics - Chemical bonding | Britannica
Advanced ceramics - Advanced ceramics - Chemical bonding: Reaction sintering, or reaction bonding, is an important means of producing dense covalent ceramics. Reaction-bonded silicon nitride (RBSN) is made from finely divided silicon powders that are formed to shape and subsequently reacted in a mixed nitrogen/hydrogen or nitrogen/helium atmosphere at 1,200 to 1,250 °C (2,200 to 2,300 °F
