Abstract

Transparent solid solution crystals of Sr[CeZr]_0.95Yb_0.05O₃ were grown by the FZ-method using a Xe-arc imaging furnace to investigate proton conductivity in mixed perovskite-type oxides. It is observed that there are at least five different O-H stretching vibrational modes in these solid solutions and their intensities and peak wave numbers depend on the composition of Ce and Zr. The results of electrical conductivity showed that these materials are proton conductors as well as SrCe_0.95Yb_0.05O₃ and SrZr_0.95Yb_0.05O₃. The IR-absorption intensity and the electrical conductivity have their maxima at x = 0.8 in Sr[Ce_xZr_1-x]_0.95Yb_0.05O₃. The Raman spectra of solid solutions suggest that the lattice distortion was changed by addition of SrZr_0.95Yb_0.05O₃ to SrCe_0.95Yb_0.05O₃.
