ELECTROSYNTHESIS AND ELECTROCHEMICAL-BEHAVIOR OF UNUSUAL SOLID THALLIUM-BASED PHASES - THALLIUM PEROXIDE, THALLIUM(I)-THALLIUM(III) MIXED-OXIDE, THALLIUM CUPRATE, AND THALLIUM OXYFLUORIDE

Possibilities are demonstrated of varying the modes and conditions of anodic electrocrystallization in order to modify the mechanism of this process and to obtain, together with Tl2O3, other oxide phases on dif ferent substrates from Tl+ solutions. Using the methods of voltammetry , chronopotentiometry, gravimetry, Auger spectroscopy, and X-ray diffr actometry, individual phases of thallium peroxide, a mixed-valence oxi de, cuprate, and oxyfluoride synthesized by this process were characte rized. For the first time, the boundaries of the thermodynamic stabili ty regions were estimated for poorly studied thallium oxide phases in aqueous solutions.
