摘　　要：聚合物前驱体裂解转化法是制备陶瓷材料的重要方法之一,裂解是该工艺中不可或缺的步骤。传统的陶瓷前驱体热裂解方法存在升降温速率慢、工艺时间长、能耗高等问题。激光裂解、微波裂解、放电等离子烧结等新技术因具有升降温速率快、能量消耗低等优势,近年来受到材料领域研究者的关注。本文总结了快速裂解方法用于硅基前驱体转化陶瓷方面的研究进展,阐述了裂解新技术在高性能陶瓷材料制备中的技术优势。The polymer precursor derived ceramics route is one of the important ways for the preparation of ceramics,and pyrolysis is absolutely necessary in the process.The traditional thermal pyrolysis suffers from slow heating/cooling rate,long processing time,and high energy consumption.In recent years,new technologies,including laser pyrolysis,microwave treatment,and discharge plasma sintering,have attracted the attention in the researchers due to the advantages of fast heating/cooling rate and low energy consumption.This paper summarizes the research progress in rapid pyrolysis in PDCs.The advantages of the new technologies in the preparation of high-performance ceramics are also discussed.
