Abstract
Pb1-xVxO2-x(OH)x (0 <x ≤0.30) solid solutions with the rutile structure were prepared by reacting humid β-PbO2 + V2O5 mixtures at temperatures from 200 to 250°C. At higher vanadium contents, lead hexavanadate, PbV6O16, was formed, as inferred from IR spectroscopy data. The structural and electrical properties of the solid solutions were studied, and the valence state of the constituent ions was determined. All of the vanadium has a valence of 4+ forx ≤ 0.06 and 5+ forx > 0.15. The lead ions are in the oxidation states 4+ and 2+ over the entire range of solid solution
