【摘要】 研究了一系列ＢａＰｂＯ３掺杂的钛酸锶铅基陶瓷的制备过程和电学性能，结果表明：低阻的ＢａＰｂＯ３的添加能显著降低材料的烧结温度，促进晶粒生长，但并不能明显降低材料的室温电阻率，ＸＰＳ分析证实了ＢａＰｂＯ３加入后在与（Ｓｒ，Ｐｂ）ＴｉＯ３固溶时，四价的Ｐｂ被还原为二价，ＢａＰｂＯ３不以低阻相单独存在更多还原

【Abstract】 A series of studies on processing and electrical porperties of (Sr,Pb)TiO 3 ceramics doped by BaPbO 3 were made. The research results indicated that the doping of BaPbO 3 could decrease the sintering temperature remarkably and promote the grain growth. However, it could not reduce the resistivity at room temperature of (Sr,Pb)TiO 3 materials. XPS analysis proved that the Pb 4+ ions were reduced to Pb 2+ ions after BaPbO 3 was doped into (Sr,Pb)TiO 3 ceramics. BaPbO 3 did not exist as low resistivity phase.更多还原
