Ceramic-forming compounds based on polycarbosilane and modified polyorganosilazanes

详细

Ceramic-forming compounds based on polycarbosilane and polyorganosilazanes modified with atoms of refractory metals (Ti and Zr) were studied. The curing and pyrolysis of the compounds in an inert medium and the thermal oxidation resistance of ceramic pyrolysis residues were examined by synchronous thermal analysis and extraction. A ceramic matrix composite material was prepared from the compounds studied and a carbon reinforcing filler, and the physicochemical properties and thermal oxidation resistance of this material were evaluated.
