STRUCTURE AND PROPERTIES OF CATION-DEFICIENT BISMUTH AND VANADIUM CONTAINING CaMoO — BASED SOLID SOLUTIONS

The article is devoted to the synthesis, determination of structural features, electrical conductivity and pigment characteristics of cation-deficient scheelite-type CaBiФMoVO solid solutions. Complex oxides were studied with X-ray diffraction and Raman spectroscopy. The concentration ranges of existence of different types and distortion of structure were discussed via the element ordering in 4 sublattice. The total electrical conductivity of the compounds was studied by impedance spectroscopy in the temperature range of 400–650°C. Arrhenius plots of electrical conductivity on the inverse temperature were constructed and analyzed. According to the diffuse light scattering data of powders, functions of color coordinates of the solid solutions were calculated.
