摘要
Abstract
Novel polyzirconosilane resin was prepared by Wurtz-Fittig copolymerization of amine stablized zirconium chloride, methyldichlorosilane and trimethylchlorosilanes, for the application of single source precursor of SiC-ZrC multicomponent ceramic (zirconium content was easily tailored).The polyzirconosilane resin was viscous liquid at ambient conditions,and its rehology was readily tailored catering to the composite process of PIP technique(Precursor-Infiltration-and-Pyrolysis).The polyzirconosilane resin underwent thermal cure at 110~200℃ to form yellowish solid,and the cured polyzirconosilane was transformed to SiC-ZrC monolith at a yield of >60% at 1 000~1 400℃. The polyzirconosilane derived SiC-ZrC exhibits ultra-high thermo-oxidation resistance in air atmophere at high temperatures.The polyzirconosilane preceramic resin would be an ideal candidate for ultra-high temperature ce-ramics in the applications of oxidation conditions.关键词
