本论文在单独研究了几种聚合物先驱体的热解行为的基础上，对多个聚合物先驱体+充填剂体系的反应热解过程中的各种物理、化学变化作了深入探讨，继而研究了由此制备的复相陶瓷的相组成、显微结构和性能的形成和变化规律。

Two polysiloxanes (SR2 and P67) and one polycarbosilane were chosen as preceramic polymers. TG-DTA-MS, FT-IR, XRD,〓Si MAS-NMR, SEM, TEM, SAD, HREM, chemical analysis and density measurement techniques were used to study the cross-linking and pyrolysis mechanisms of the preceramic polymers. The development of chemical composition and structure, density, phase composition and microstructure of the solid pyrolyzed products during pyrolysis process were systematically investigated. While pyrolysis temperature approached 1000℃, ceramization process of the preceramic polymers almost completed, and ceramic yield of the preceramic polymers hardly changed any more.
