Research Progress in Rapid Pyrolysis and Conversion of Silicon Based Ceramic Precursors
The polymer precursor derived ceramics route is one of the important ways for the preparation of ceramics,and py-rolysis is absolutely necessary in the process.The traditional thermal pyrolysis suffers from slow heating/cooling rate,long pro-cessing 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.
