摘　　要：航空航天、兵器、能源等高科技领域的发展对轻质、耐高温的超高温陶瓷材料提出了迫切需求。硼化锆基超高温陶瓷是最重要的超高温陶瓷材料之一,综述了硼化锆基超高温陶瓷的研究进展,着重探讨了先驱体转化法制备硼化锆基超高温陶瓷的优势和难点,并对硼化锆基超高温陶瓷的发展进行了展望。With the development of aerospace,weapons, and energy, ultrahigh temperature ceramics （ UHTCs ） are urgently required. Zirconium boride （ ZrB2 ） ceramics, one of the most important UHTCs, has received considerable attention due to its excellent high temperature resistance. The developments of ZrB2-based ceramics are reviewed in the paper. The advantages, as well as the difficulties of ZrB2 -based ceramics by polymer-derived technique are discussed. The future development of ZrB2-based ceramics is also prospected.
