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.
