我们描述了一种一锅法合成杂化锆碳化硅材料的新方法。在ZRC粉末存在下，由三甲基乙烯基硅烷生成聚碳硅烷。聚合物与陶瓷颗粒之间存在着特殊的相互作用。热重分析、热解测试和扫描电子显微镜观察表明，这些杂化材料在850℃以上保持稳定，总质量损失小于20%。
We describe a new route to synthesize hybrid ZrC–SiC materials in a one-pot procedure. Polycarbosilane was generated from trimethylvinylsilane in the presence of ZrC powder. A specific interaction between the polymer and the ceramic particles was evidenced. The conversion of precursor into composite was achieved by pyrolysis under argon up to 1100°C. From thermogravimetric analyses, pyrolysis tests and SEM observations, it has been shown that these hybrid materials kept a stability above 850°C, and their total mass loss remained lower than 20%.
