In the paper, a comprehensive systematic study of different classes of bismuth containing oxide compounds was carried out. The relationship between composition, temperature and concentration regions of existence of stable, specific structure and properties of solid solutions on the basis of vanadates, molybdates, niobates and bismuth was found. The general regularities of synthesis of solid solutions with different variants of solid-phase and soluble methods were determined. On this basis, the optimal conditions for obtaining single-phase materials were formulated. For the first time the temperature and concentration boundaries of the regions of homogeneity and areas of stable existence of polymorphic modifications of solid solutions were defined and/or refined. The structural parameters of the synthesized phases were determined. By the method of electrochemical impedance spectroscopy the nature and features of impedance spectra, the temperature and concentration dependences of electrical conductivity of ceramic materials based on bismuth containing complex oxides were identified.

Single phase samples of bismuth molybdate, Bi26Mo10O69, doped with Mn on the bismuth sublattice and V, Fe on the molybdenum sublattice were found to crystallize in the triclinic Bi26Mo10O69 structure at low doping levels and in the monoclinic Bi26Mo10O69 structure - at higher dopant concentration. The assumption that all Mn ions have an oxidation state of +2 was confirmed by means of magnetic measurement results analysis using Curie-Weiss law. Conductivity was investigated using impedance spectroscopy. The conductivity of Bi26.4Mn0.6Mo9.6Fe0.4O69-d was 1.2*10-2 S*cm-1 at 973 K and 2.2*10-4 S*cm-1 at 623 K, and the conductivity of Bi26.4Mn0.6Mo9.2V0.8O69-d was 2.2*10-3 S*cm-1 at 973 K and 2.2*10-5 S*cm-1 at 623 K.

Cobalt-Doped Bi 26 Mo 10 O 69 : Crystal Structure and Conductivity. -The complex oxides Bi1-xCox[Bi12O14]Mo5O20±δ (x = 0.1-1) and Bi[Bi12O14]Mo5-yCoyO20±δ (y = 0.2, 0.4) are synthesized by solid state reactions of stoichiometric mixtures of Bi2O3, MoO3, and Co3O4 (alumina crucible, 673-1123 K). The samples are characterized by powder XRD, neutron powder diffraction, SEM, TEM, and impedance spectroscopy. The new compounds Bi 0.8 Co 0.2 [Bi 12 O 14 ]Mo 5 O 34.5±δ and Bi[Bi 12 O 14 ]Mo 4.8 Co 0.2 O 34.5±δ crystallize in the monoclinic space group P2/c with Z = 2. The materials are good ionic conductors with similar conductivity values as yttrium substituted zirconia and gadolinium substituted ceria. -(MIKHAILOVSKAYA*, Z. A.; BUYANOVA, E. S.; PETROVA, S.
