Taking into account the relevance of obtaining environmentally friendly materials with desired properties and the need for ionic conductors, we present the results of the synthesis and studies of oxygen-conducting La2O3 o 2MoO3 ceramics. Ceramic samples were obtained by the solid-phase method from the initial lanthanum oxides La2O3 o and molybdenum MoO3. Using the methods of dielectric spectroscopy, using AC bridges P5083 and E7-12, the conductive properties of single-phase solid solutions were studied, and the presence of a phase transition at a temperature of about 560 ° C was established. Temperature hysteresis in the mode of heating - cooling showed that the phase transition of the first kind. The results of studies of the dielectric properties of the obtained ceramics at various frequencies and at direct current revealed that the high conductivity observed in molybdate is ionic in nature and occurs due to the movement of oxygen ions.
