| 摘 要： | 本文用扫描电子显微镜和微区能谱分析研究了Ｎｂ掺杂浓度对多孔ＢａＴｉＯ３陶瓷显微结构及半导化性能的影响；对Ｎｂ掺杂浓度在半导化组分附近的样品中产生的半导化不均匀现象进行研究，认为产生这种现象的主要原因是由于样品中的Ｎｂ元素在烧成过程中通过表面向外界扩散引起的。

| Abstract: | The effect of amount of Niobium dopant on microstructure and semiconductingproperties of porous BaTiO3 ceramics were studied by SEM and ELS. The semiconductionnon-uniformity found in ceramics samples nearby the semiconducting composition was inves-tigated. It is deemed that the semiconduction non-uniformity is caused by diffusion of Nb dur-ing sinting peiod of the ceramic samples. |
