导电体与绝缘体复相陶瓷的导电性能符合渗流理论 ,其渗流转变曲线受多种因素的影响 ,除导电相与绝缘相二相组成的配比外 ,还受到二相颗粒的尺寸、形状及分布的影响 ,复相陶瓷的烧成温度、温度制度影响了临界指数、晶粒粒径比及晶界层 ,从而也影响渗流转变曲线 The electrical conductivity of composite ceramics with conductor and insulator conforms to seepage theory. The seepage flow curve is affected by many factors. In addition to the composition of two phases of conductive phase and insulating phase, the two-phase particle size, shape and distribution The influence of the sintering temperature and temperature of the multiphase ceramics on the critical exponent, the grain size ratio and the grain boundary layer also affect the seepage transition curve
