Abstract

WE have previously reported successful production of a high-strength continuous SiC fibre1–3, a high flexural strength SiC sintered body4 and a heat-resistant Fe–Cr alloy5 by converting organometallic polymer polycarbosilane (PC) as the binder to an inorganic in thermal decomposition. We then found that in the thermal decomposition of organometallic polymers such as PC, an amorphous state exists before formation of the (SiC) fine particles; this SiC amorphous state is hardly possible in inorganic reactions. The process of thermal decomposition of organometallic polymers is little known. To obtain general information on the phenomenon, we have newly synthesised multi-element polyborodiphenylsiloxane containing oxygen (B, C, Si, O, H) compared with PC composed of Si, C and H, and observed the process of its thermal decomposition.
