Abstract:
Chloro-species of molybdenum in oxidation states (III), (IV) and (V) were studied in a range of alkali chloride melts employing high temperature electronic absorption spectroscopy. The reaction rates of disproportionation of MoCl6 3- complex ions in various melts between 550 and 750 °C were determined. Mo(IV) species MoCl6 2- were generated and thermodynamic properties of Mo(IV) chloride in NaCl-CsCl eutectic melt estimated. Absorption spectra of molybdenum(V) MoCl6 - were measured in a chloride melt for the first time. Speciation and behavior of molybdenum is required for designing processes for molten salt reprocessing of spent nuclear fuel (SNF). ©The Electrochemical Society.
