Summary

Several commercially available pofyorganosilazanes were examined for application as preceramic binders in ceramic composites composed of a reaction bonded silicon nitride matrix reinforced with silicon carbide fibers. Processing parameters were shown to affect the ceramic yield and dimensional stability of the “neat” polysilazanes. FTIR was used to monitor changes in the chemical structure of the pofysilazanes during the cure and pyrofysis steps. Ceramic samples using these pofysilazanes as preceramic binders were compared to control samples.
