摘　　要：从研究中温加热用ＰＴＣ效应热敏陶瓷材料的成分，性能与工艺之间的关系入手，在传统耻，通过不同掺杂量和烧结工艺对ＰＴＣ效应半导资性能影响的分析，选出最佳成份配比与最佳烧结工艺。介绍从配料到终烧的各个步骤。This paper deals with the relations of components and properties with techniques of PTC thermal sensitive ceramic material which is used in heating of middle temperature. On the basis of conventional process, by analyzing influence of different quantity of dopants and techniques on PTC properties, optimum components and techniques are chosen.Each step from components choosing to final sintering is introduced in detail. The resultsshow that the PTC materials researched are endowed with well stability, good PTC effect and simple technology.
