| dc.description.abstract | The crystal, electrical and electrochemical properties of the new composite materials of (1-x)SrTi0.5Fe0.5O3-δ-xCe0.8(Sm0.8Sr0.2)0.2O2-δ (0≤x≤1, Δx= 0.25) prepared by solid phase method. Composites have no phase interaction. The increase of the fluorite phase conductivity increased in the reducing atmosphere, and decreased in the oxidation atmosphere. The oxygen permeability was 3×10-7 mol/(cm2 s) at 1173 K{cyrillic} and log(p1O2/p2O2)=1. The value of the effective ambipolar conductivity calculated from the obtained data of the oxygen permeability (10.7 mS/cm) is lower with the average ambipolar conductivity obtained from its log σ ÷ log pO2-dependence (67.6 mS/cm) for the sample 0.5SrTi0.5Fe0.5O3-δ-0.5 Ce0.8(Sm0.8Sr0.2)0.2O2-δ Copyright © 2013 Delta Energy and Environment. | en |
