Abstract
1 min read
Reactions leading to the formation of uranyl(V) species in fused alkali chlorides were studied. The reactions investigated include thermal decomposition of uranyl(VI) chloride in alkali chloride melts, electrochemical and chemical reduction of UO22+ ions in LiCl, 3LiCl-2KCl, NaCl-KCl and NaCl-2CsCl melts at 550-850 oC. Elemental tellurium, palladium, silver, molybdenum, niobium and zirconium were tested as the reducing agents. The outcome of the reaction depends on the electrochemical properties of the reductant.
