Polymer-derived route is an important method for the preparation of high-performance ceramic materials, especially in the fabrication of continuous fibers and fiber reinforced ceramic matrix composites (FRCMC), which has significant advantages in terms of composition and microstructure modulation. Based on adjustable multi-element contents and controllable chemical bonding structure of precursors, polymer-derived SiBCN ceramics are discovered with various structural features and special properties. In recent years, the development of structure-function integrated SiBCN ceramics has received extensive attention. In this paper, we mainly focused on the research progress of precursor-derived SiBCN ceramics from 2016 to the present, firstly briefly introduced the common features of precursor-converted SiBCN ceramics, and then summarized the important advances in four areas: SiBCN ceramic precursors and pyrolyzed products, continuous SiBCN ceramic fibers, SiBCN matrix composites, and functional SiBCN ceramics, raised research prospectives and priority proposals in the final section. This tourism review is expected to provide a reference for the research and development of SiBCN ceramics, and to promote the application of SiBCN-based ceramic materials.
