Resumo
The results of structural and electrophysical characterization of substituted bismuth niobates Bi3Nb1 – xErxO7 – δ , promising oxygen-ion conductors, are presented. The homogeneity extents were determined and crystallochemical parameters of solid solutions were calculated using X-ray powder diffraction and electron microscopy with energy-dispersive microanalysis (SEM-EDX). The stability of the solid solutions and the occurrence of phase transitions in them were determined by differential scanning calorimetry and dilatometry. The electrical conductivity of sintered samples was studied by impedance spectroscopy.
