Boron carbide (B4C) is a kind of advanced ceramics with excellent properties, which has been widely applied in military, nuclear, aerospace, and other high-tech fields. The fabrication of boron carbide by precursor derived method has been well developed in recent years. Comparing with other preparative approaches, the pre-cursor derived method has a variety of advantages including simple elemental composition, good formability, high ceramic yield, and low energy consumption, which has been widely applied to prepare boron carbide powder, fibers, mesoporous ceramics and ceramic microspheres. In this paper, current development of boron carbide pre-pared by precursor derived method was reviewed. Synthesis and application of boron carbide precursors were mainly discussed. In addition, the future efforts and application prospects of precursor-derived boron carbide ce-ramics were also analyzed.%碳化硼(B4C)是一种性能优良的特种陶瓷,在军事、核工业、航空航天等领域有着广泛的应用.近年来,采用先驱体转化法制备碳化硼陶瓷得到了长足的发展.相比碳化硼材料的其它制备方法,先驱体转化法具有元素组成简单、成型性好、陶瓷产率高、能耗低等优势,在制备碳化硼粉体、纤维、介孔材料、微球等方面有着广泛的应用.本文综述了先驱体转化法制备碳化硼陶瓷的最新研究进展,着重介绍了碳化硼先驱体的合成及应用,并对先驱体转化法制备碳化硼陶瓷的发展方向和应用前景进行了展望.
