| dc.description.abstractEn | BiMeVOx compounds Bi4V2-xCux/2Nbx/2O11-3x/4 doubly substituted solid solution, with identical compositions of Cu2+ and Nb5+ ions, show an area of existence from x = 0 to 0.5. X-ray diffraction measurements and thermal analysis have shown that, depending on the composition, the three main Bi4V2O11 polymorphs α, β and (γ/γ′) are observed at room temperature. The evolution of the electrical conductivity with the rate of substitution has been investigated by electrochemical impedance spectroscopy (EIS) in the temperature range 120–720 °C. The highest values of conductivity are observed for samples with x = 0.2. Scanning electron microscopy (SEM) shows an important grain growth and the presence of micro-cracks in the ceramics with x = 0.5 composition. | |
