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

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
