The formation of pyrochlore phase is inhibited by secondary synthesis,meanwhile the synthesis temperature of perovskite phase is decreased, reducing the volatilization of PbO in maximum.

二次合成法抑制了焦绿石相的生成,同时降低了钙钛矿相的合成温度,最大限度地降低了PbO的挥发。

Being major subject, high-temperature proton conductors based on pyrochlore-type or fluorite-type oxides are reviewed concerning their structure properties, conductivities, conduction mechanism as well as the study status.

本文的研究对象是萤石型高温质子导体和烧绿石型高温质子导体,因此文章中对这两种质子导体的结构特点、离子传导机理、离子传导特性,以及在国内外的研究现状作为详细的阐述。

It turns out that for Er_2Hf_2O_7 the defect fluorite structure is more stable than pyrochlore structure, agreeing well with previous investigations.

计算结果表明,Er_2Hf_2O_7的缺陷萤石结构比烧绿石结构更稳定,这与以前的研究结果是一致的。
