Preparation,Properties and Application of Polymer-Derived SiBCN Ceramics

先驱体转化法是制备高性能陶瓷材料的重要方法,尤其在连续纤维及其复合材料(FRCMC)的制备、元素组成与微结构调控等方面具有显著优势。先驱体转化SiBCN陶瓷具有多元素含量可调、化学键合结构可控的特点,构建了不同结构特征和特殊性能的陶瓷材料。近几年,先驱体转化SiBCN陶瓷发展呈现出新的特点,结构功能一体化设计与制备技术受到了国内外的广泛关注。本文主要梳理了2016年至今先驱体转化SiBCN陶瓷的国内外研究进展,首先简要介绍先驱体转化SiBCN陶瓷的主要特点,然后以先驱体转化陶瓷产物的典型特点为分类依据,分别从SiBCN陶瓷先驱体及其陶瓷产物、连续SiBCN陶瓷纤维、SiBCN基复合材料和功能化SiBCN陶瓷4个方面综述了主要研究进展,提出了未来发展趋势和重点任务,期望为SiBCN陶瓷研制与应用研究提供参考,促进我国先进陶瓷材料的发展进步。

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 ceramicfibers,SiBCN matrix composites,and functional SiBCN ceramics,raised research prospectives and priority proposals in thefinal 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.
