Synthesis and Conductivity of Bismuth Molybdates Doped with Antimony and Tin

The possibility of synthesizing oxygen-ion conductors based on bismuth molybdate with antimony and tin substituted to the molybdenum sublattice is studied and the specific features of their structure and properties are elucidated. For these compositions, the regions of homogeneity are determined and structure peculiarities are investigated. The unit cell parameters and the volume density of samples are determined. By IR spectroscopic studies, the characteristic frequencies of the metal-oxygen bonds are determined. The total conductivity of compositions is studied by impedance spectroscopy in the temperature interval from 200 to 825 degrees C. The temperature dependences of conductivity are plotted and its dependences on the concentration are analyzed.
