The present work is devoted to the investigation of the methods of a synthesis and properties of the one of the most interesting one-dimensional oxygen –ion conductors, the Bi 13 Mo 5 O 34± δ –based complex oxides. The general compositions of these bismuth molybdates are Bi 13 Mo 5- х Me х O 34- δ , and Bi 13-y Me y Mo 5 O 34- δ , with Me = Mg, Ca, Sr, Ba (IIA group) and Co, Fe, Ni (Fe triade). The samples have been synthesized using conventional ceramic technology. The powders and pellets of the bismuth molybdates were studied by X-Ray diffraction, scanning electron microscopy, laser dispersion, dilatometry, atom absorption and inductively-coupled plasma atomic emission spectrometry. Electrical conductivity has been studied using impedance spectroscopy method.
