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.
