Abstract: The characteristics and development of ceramics prepared by preceramic polymer pyrolysis were reviewed. The disadvantages of such method, high porosity and large shrinkage of ceramics obtained, and the means to overcome these disadvrantages were included. Adding active fillers as one of the means was described in detail, and to select the fillers four principles were proposed. The development at home and abroad of the active fillers controlled polymer pyrolysis was also reviewed.

Key words: preceramic polymer, active filler, ceramics
