Abstract Pristine as well as ytterbium substituted barium thorates, BaTh 1-x Yb x O 3-δ (x = 0–0.2) were synthesized using a modified solid state method. Electrical conductivity behavior of the sintered specimens in various atmospheres in temperature range from 300 to 600 °C was explained. Substitution of ytterbium into barium thorate was found to enhance its conductivity in oxygen ambience. The same was found to be enhanced further when the ambience was changed to hydrogen for the composition up to x = 0.1 but, marginally decreased from thereon for the composition with x = 0.15. Retention of hydrogen in thorate matrix was elucidated.

BaTh 1-x Yb x O 3-x/2 的合成、表征和电导率

摘要 使用改进的固态方法合成了原始和镱取代的钍钡 BaTh 1-x Yb x O 3-δ (x = 0–0.2)。解释了烧结样品在 300 至 600 °C 温度范围内各种气氛中的导电性能。发现将镱置换为钍酸钡可增强其在氧气环境中的电导率。当环境变为氢气时，对于高达 x = 0.1 的组合物，同样被发现进一步增强，但对于 x = 0.15 的组合物，自此略微降低​​。阐明了氢在钍酸盐基质中的保留。
