Abstract

Chemical reduction of uranyl(VI) ions was studied in melts based on NaCl-2CsCl, NaCl-KCl, 3LiCl-2KCl and LiCl between 550 and 750°C by high-temperature electronic absorption spectroscopy and electrochemistry. Elemental hydrogen, zirconium, niobium, molybdenum, silver, palladium, tellurium and Nb(III) chloro-species were used as the reducing agents. The products formed depend on temperature, melt composition and the nature of the reductant.
