Electrical Properties of (1–x)La2Mo2O9-xLa2Mo3O12 (x = 0.15) Composite System


Electrical properties of (1–x)La2Mo2O9 –xLa2Mo3O12 (x = 0.15) composite system are
investigated. Introduction of an inert additional phase La2Mo3O12 (adjacent phase to La2Mo2O9 in the phase diagram) results in an increase in conductivity of composite by approximately one order of magnitude. This increase is associated with the appearance of a composite effect. The dominant ionic conductivity is maintained in
the wide range of oxygen partial pressures. The calculated ion transport numbers are close to 1.
