Abstract
New solid electrolytes with a high rubidium-cation conductivity, which are based on Rb3PO4 with partial substitution of three-charged yttrium, lanthanum, and neodymium cations for Rb+ cations, are synthesized and studied. Introduction of M3+ cations leads to an abrupt increase in the conductivity of rubidium orthophosphate due to the formation of cationic vacancies and stabilization of high-temperature cubic β-modification of Rb3PO4. In all systems, the highest conductivity is observed in the single-phase region of β-phase existence: it is ~10–1 S cm–1 at 700°C and above 10–2 S cm–1 at 400°C. The factors, which have an effect on the transport properties of studied electrolytes, are considered.
