Applications of Active Filler in the Preparation of Preceramic Polymer Derived Ceramics

Keywords： preceramic polymer , active filler , ceramics

综述了用先驱体法制备陶瓷材料的特点，针对先驱体法气孔率高及收缩率大的不足，提出了三个解决办法，其中着重讨论了活性填料的选择原则及其在先驱体裂解制备陶瓷中的特点、应用国内外研究现状.

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 disadvantages 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.
