Abstract: A series of cobalt-doped bismuth molybdates were synthesized and investigated using X-ray powder diffraction, transmission electron microscopy and impedance spectroscopy. The ranges of solid solution were determined. Two new compounds, Bi1-xCox[Bi12O 14]Mo5O34.5 ± δ (x=0.2) and Bi[Bi12O14] Mo5-yCoyO34.5 ± δ (y=0.2), which crystallise in monoclinic unit cells have been examined in detail by diffraction methods. Impedance spectroscopy measurements show that the studied materials are good ionic conductors with conductivity values about 5 × 10-3 S × cm-1 at 973 K and 1.7 × 10-4 S × cm-1 at 623 K, which are similar to conductivity values of yttrium substituted zirconia and (YSZ) gadolinium doped ceria (CGO). © 2013 Elsevier Inc.
