SiC，Si3N4，BN等二元體系陶瓷纖維因具有優良高溫機械性能、介電性能、高溫穩定性能所以被廣泛地應用，而相比較而言多元體系SiBN(C)陶瓷纖維正處于研究的初步階段，但是因其綜合了上述二元體系的各種優點，如高溫熱穩定性、高溫耐腐蝕、抗氧化等性能所以已成為當前航空航天領域的研究熱點，尤其是含碳量很低的SiBN陶瓷纖維具有很好的透波性能，在導彈天線罩上有重要的應用。其中前驅體聚合物轉化法是SiBN(C)陶瓷纖維的主要制備方法，該方法的優點在于可通過前驅體聚合物的分子結構設計，得到含有目標元素的分子前驅體，并在聚合過程中調控其流變性能，從而獲得具有可紡性的前驅體聚合物。主要概述了近年來國際和國內采用前驅體聚合物轉化法制備SiBN(C) 陶瓷纖維的幾種方法，它們分別是含硼分子改性聚硅氮烷法，單體改性硼基前驅體法和小分子單體合成法。其中小分子單體合成法又分為多步法和一步合成法。用圖表分析比較了各種方法的合成路線，SiBN(C) 陶瓷纖維制品性能，以及存在的問題，并且提出了進一步研發的方向和建議。

Binary system SiC，Si 3N 4，BN has served already in industrial application with isolated merit, for instance high temperature mechanic properties，excellent dielectric properties and high temperature thermal stability respectively. Although SiBN(C) ceramic fibers still wander at the outset of research, combining merit of various binary ceramic fibers, are expected to possess comprehensive properties, including high temperature stability and oxidation resistance at high temperature, particular in excellent wavetransparent, it will play an important role in random application Precursor polymerderived ceramic is the main method to produce SiBN(C) ceramic fibers, by which one can design the molecular structure of precursor polymer, the molecular precursor with objective elements can be obtained. Furthermore, the precursor polymer with good spinnability can be obtained by controlling its rheological properties during the polymerization. Three methods for preparing SiBN(C) ceramic fibers were reviewed in this paper, boronsubstituted polysilazane, boronbased polyborlysilazane, molecular preparation of polyborlysilazane. The small molecule monomer synthesis also can be divided into multipot and onepot synthesis method. Chart comparing the synthesis route , performance of SiBN (C) ceramic fiber products , as well as the existence of the problems for various methods, and the directions and recommendations for further research and development were put forward finally.
