Abstract
Ba1−xLaxSc1−yZryO3−δ with perovskite-related structure was synthesized by dopes of La and Zr to Ba-site and Sc-site of Ba2Sc2O5, respectively. The lattice parameters were refined by the Rietveld analysis with space group Pm3m. The total electrical conductivities of Ba1−xLaxSc1−yZryO3−δ measured by DC four-probe method were found to be about 10− 2 S·cm− 1 at 1000 °C in air and contributed by oxide ion, proton, and hole. The oxide ion transport number of Ba1−xLaxSc1−yZryO3−δ determined by ion blocking method increased with decreasing temperature.
