摘要
采用均匀设计液相涂覆热扩散方法，研究了涂覆离子，热扩散条件等对SrTiO3系陶瓷电性能的影响；用扫描电子显微镜（SEM）作微观分析，X射线能谱仪作元素分析，证实钠离子（Na＋）的涂覆热扩散未在陶瓷晶粒之间产生新相，钠离子（Na＋）在晶粒内表面形成了一扩散层，讨论了扩散条件与电性能的内在联系．
The effect of thermal diffusion on electrical properies of SrTiO3 multi-function ceramics with coating ion was studied by application of the even design expermental method. Microstructure and element analysis were examined by SEM and Energy-Dispersive X-Ray analyss (EDX) techenolegy. No new intergranuar phrase were oberved.The relationship amang electrical properties,diffusion conditions of the materials were discussed.
