Abstract:

The behavior of molybdenum(III), tungsten(IV), and uranium(VI) ions in NaCl-2CsCl-eutectic-mixture-based melt at 550°C is studied by spectroelectrochemical method. Anodic oxidation of MoCl63- and WCl62- yields melt-soluble chloride compounds MoCl62- and WCl6-, respectively. It is shown that the electrochemical recharging in the Mo(III)/Mo(IV) system is reversible; the formal standard potential E*Mo(IV/Mo(III)) and the Gibbs energy ΔG*MoCl4(melt) are evaluated. The cathodic reduction of U(VI) yields U(V) ions. The cathodic reduction of W(IV) ion does not yield melt-soluble tungsten compounds of lower oxidation state. © Pleiades Publishing, Ltd., 2010.
