摘要
对ＬａｘＢａ１－ｘＣｏＯ３系导电陶瓷的导电性及其导电机制进行了研究，在ｘ＝０５ｍｏｌ处，导电陶瓷具有金属态导电性。在Ｌａ０．５Ｂａ０．５ＣｏＯ３陶瓷中，存在着氧缺位和导电电子，并且此种导电陶瓷具有较高的电子和氧离子混合导电特性。
The conductivity and their conductive mechanism of La x Ba 1- x CoO 3 ceramics were studied while x equals 0 5 mol, and the conductivity is of the metallic state conductivity. There are oxygen vacanies and conductive electrons in La 0.5 Ba 0.5 CoO 3 ceramic, and this ceramic possesses highly mixed conductivity of electrons and oxygen ions.
