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.
