Transport properties of metacomposites in eutectic MAO4–V2O5 systems (M = Ca, Sr; A = W, Mo)

Transport properties of metacomposites in eutectic MAO4–V2O5 systems (M = Ca, Sr; A = W, Mo) Metal molybdates MMoO4 (M = Ca, Sr) and their composites with vanadium oxide V2O5 were synthesized. An X-ray diffraction analysis confirmed that the obtained molybdates were single-phase, and the heterogeneous systems were two-phase. The temperature dependences of the total conductivity of the composites were studied. The ion transport numbers in the {CaMoO4 · xV2O5} composites (x = 1–30 mol %) were studied by the EMF method.

Abstract

Metal molybdates MMoO4 (M = Ca, Sr) and their composites with vanadium oxide V2O5 were synthesized. An X-ray diffraction analysis confirmed that the obtained molybdates were single-phase, and the heterogeneous systems were two-phase. The temperature dependences of the total conductivity of the composites were studied. The ion transport numbers in the {CaMoO4 · xV2O5} composites (x = 1–30 mol %) were studied by the EMF method. The conductivity of the composites at x ≤ 5 mol % was shown to be ionic. The conductivity of the composites was described using the mixing equation.
