Synthesis and Characterization of New Precursors to Nearly Stoichiometric SiC Ceramics .1. The Copolymer Route
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 spectroscopies, size exclusion chromatography and thermogravimetric analysis. These precursors give SIC ceramics with a C/Si (atomic ratio) approximate to 1.14 and a relatively low oxygen content (between 1.5-3 at %).
