Summary:Solid solutions Bi 3 Nb 1– y W y O 7 ± δ , Bi 3 Nb 1– y V y O 7 ± δ , Bi 3 Nb 1– y Fe y O 7 ± δ ( y = 0.1–0.5; Δ y = 0.1), and Bi 3– x Y x Nb 1– y W y O 7 ± δ ( x = 0.05, 0.1; y = 0–0.3; Δ y = 0.1) have been studied. The homogeneity ranges of the solid solutions and crystal-chemical parameters have been determined by means of X-ray powder diffraction. The electrical conductivity of sintered samples has been studied by impedance spectroscopy. The joint introduction of yttrium and tungsten into the niobium sublattice does not lead to an increase in the conductivity of solid solutions, and the change of the dopant type has no noticeable effect on this conductivity.
