N2 - Abstract: (1 – φ)La2(WO4)3–φAl2O3 composites are obtained by the solid-phase method (φ is the volume fraction of nanodispersed alumina) and their thermal properties, morphology, and electrical conductivity are studied depending on temperature, pressure of oxygen in the gas phase, and composition. It is found that the conductivity of the composites (1 – φ)La2(WO4)3–φAl2O3 passes through a maximum at φ ~ 0.1 and reaches a value of 7 × 10–3 S/cm at 1000°C, which is seven times higher than the conductivity of La2(WO4)3 at the given temperature. Using the EMF method and measuring the dependence of electrical conductivity on oxygen pressure in the gas phase, the ionic nature of the conductivity of the (1 – φ)La2(WO4)3–φAl2O3 composites is established. © 2023, Pleiades Publishing, Ltd.
