纤维用含硼 SiC 陶瓷先驱体的研究进展

摘要

综述了硅硼碳（SiBC）先驱体、硅硼碳氧（SiBCO）先驱体和硅硼碳氮（SiBCN）先驱体等纤维用含硼碳化硅（ SiC）陶瓷先驱体的合成方法，分析了不同陶瓷先驱体的组成、结构和性能，比较了几种合成含硼SiC先驱体方法的优缺点，提出了纤维用含硼SiC陶瓷先驱体的合成新思路。%The present paper gives an overview of the synthesis strategies from the polymeric precursors which are used to prepare boron-containing SiC ceramic fibers , such as SiBC , SiBCO and SiBCN .The struc-tures and the properties of the derived fibers are discussed , and the advantage and disadvantage of the different methods for synthesizing boron-containing silicon carbide precursor are compared .A novel route for preparing boron-containing SiC ceramic precursor is proposed .
