- Abstract
- Composites (1-φ)La2(WO4)3 – φAl2O3 (φ is the volume fraction of nanodispersed aluminum oxide) were obtained by the solid-phase method, their thermal properties, morphology, electrical conductivity depending on temperature, oxygen pressure in the gas phase, and composition were studied. It was found that the conductivity of 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 7 times higher than the conductivity of La2(WO4)3 at 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 (1-φ)La2(WO4)3 – φAl2O3 composites was established.
