摘要: 本文合成了REF3(RE=Y、La、Ce、Nd、Gd、Tb、Dy、Er、Yb)及RE1-xBxF3-y(RE=Y、La、Ce、Gd、Yb、B=Ca、Sr、Ba)。研究了它们的结构与电学性质。La0.95Ba0.05F3-y,Ce0.95Ca0.05F3-y属固溶体,测定了新化合物Y0.71Ca0.29F3-y和Gd0.85Ca0.15F3-y的晶系。RE1-xBxF3-y的离子导电性质比REF3强。本文以RE1-xBxF3-y为基材制作了固体电解质传感器件,研究了它们对氧的敏感性质,制成了可在150℃使用的氧敏传感器。

Abstract: REF3(RE=Y. La. Ce. Nd. Gd. Tb. Dy. Er and Yb)and RE1-xBxF3-y(RE=Y. La.Ce. Gd and Yb;B=Ca.Sr and Ba)were prepared, and their structure and electric proper-ties were studied. La0.95Ba0.05F3-yand Ce0.95Ca0.05 F3-yare solid solutions. Y0.71Ca0.29F3-yand Gd0.85Ca0.15F3-yare new compounds, their lattice parameters have been calcula-ted.The RE1-xBxF3-yshowed greater conductivities than REF3. Some of oxygen sensorsmade by RE1-xBxF3-ysolid electrolytes could be used promisingly at 150℃.

Key words: Rare earth fluoride complex, solid electrolyte, oxygen sensor
