| Abstract(in English) | We have studied the ceramization of polymethylsilane (PMS) as a precursor for silicon carbide (SiC). Since as-produced PMS had a low ceramic yield (33.5%), we irradiated it by ^<60>Co γ-ray and obtained highly cross-linked polymers, the latter having a high ceramic yield up to 71%. Gas analysis of γ-ray irradiated PMS during pyrolysis indicates that PMS gives several Si-containing gases such as methylsilane caused by Si-Si scission. Evolution of such heavy gases inevitably cause weight loss. We found that ceramization of highly cross-linked polymers to SiC ceramics proceeded via three stages. |
