Аннотация

The structure of lithiated fluorite-like molybdates of the Ln5Mo3O16+δ family was studied using accurate X-ray diffraction analysis in the temperature range 20–777°C (293–1050 K). Thermally activated redistribution of oxygen ions over basic and interstitial positions and reversible change in the position occupancies upon heating–cooling were established. Thermal stability, ionic oxygen conductivity and dielectric properties of ceramic samples of undoped and Li-containing Nd5Mo3O16+δ phases were studied in the temperature range 20–900°C. The results demonstrate the possibility of controlling the functional properties of materials for use in medium-temperature solid oxide fuel cells.
