| Popis: | The solid solution La0.9Sr0.05Bi0.05Mn1 – yNiyO3 (y = 0.0–1.0) was obtained for the first time using the solid-phase method and studied. It has been found that the solid solution (y = 0.1–0.3) with a rhombo-hedral structure (space group R3c) can exist at temperatures higher that 493 K. At room temperature, only La0.9Sr0.05Bi0.05MnO3 is a single phase. The studied complex oxides are chemically inert with respect to a bismuth-containing electrolyte based on Bi3Nb1 – yEryO7 – δup to 973 K. The use of composite electrode materials La0.9Sr0.05Bi0.05Mn0.7Ni0.3O3: Bi3Nb0.6Er0.4O7 – δ(1: 1 wt %) leads to an increase in the values of electroconductivity of an electrochemical cell containing the solid electrolyte based on bismuth niobate in comparison with the La0.9Sr0.05Bi0.05Mn0.7Ni0.3O3 electrodes. |
