Abstract

Thermal and electrical properties of solid solution and compositional samples in the Ba2In2O5–Ba2InNbO6 quasi-binary system are investigated. The samples were shown to reversibly interact in a humid atmosphere at temperatures below 600°C with water vapor, to form proton defects. The hydration process is accompanied by a significant increase in the total electrical conductivity, due to the proton transfer contribution. Below 500°C in humid air the samples are predominantly the proton conductors. A compositional effect of proton electrical conductivity is established.
