Abstract

Abstract: REF₃(RE=Y. La. Ce. Nd. Gd. Tb. Dy. Er and Yb)and RE_1-xB_xF_3-y(RE=Y. La.Ce. Gd and Yb;B=Ca.Sr and Ba)were prepared, and their structure and electric proper-ties were studied. La_0.95Ba_0.05F_3-yand Ce_0.95Ca_0.05 F_3-yare solid solutions. Y_0.71Ca_0.29F_3-yand Gd_0.85Ca_0.15F_3-yare new compounds, their lattice parameters have been calcula-ted.The RE_1-xB_xF_3-yshowed greater conductivities than REF₃. Some of oxygen sensorsmade by RE_1-xB_xF_3-ysolid electrolytes could be used promisingly at 150℃.

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