At. Hemida et al., SYNTHESIS AND CHARACTERIZATION OF NEW PRECURSORS TO NEARLY STOICHIOMETRIC SIC CERAMICS .1. THE COPOLYMER ROUTE, Journal of Materials Science, 32(13), 1997, pp. 3475-3483
Organosilicon polymers with a (C/Si (atomic ratio) < 1.28) exhibiting
Si-Si and Si-CH2-Si linkages in their backbone have been prepared and
characterized by multinuclear magnetic resonance and infrared spectros
copies, size exclusion chromatography and thermogravimetric analysis.
These precursors give SIC ceramics with a C/Si (atomic ratio) approxim
ate to 1.14 and a relatively low oxygen content (between 1.5-3 at %).
