Development of ceramics, especially silicon carbide fibres, from organosilicon polymers by heat treatment

Abstract From various new organosilicon polymers many useful ceramics are obtained by heat treatments. The new polymers that have been made in my Laboratory are called Mark I, II and III. High strength SiC fibre, SiC sintered bodies, refractory alloys, and refractory polymers have been obtained from those polymers. In the process of converting organometallic polymers into SiC ceramics by heat treatment, an apparently amorphous state appears which has a parallel in the preparation of glassy carbon made by the pyrolysis of cross linked resins such as phenolformaldehyde. This glassy state of SiC has many interesting features in the fields of physics and chemistry.
