Abstract:

The reaction of uranium dioxide with excess hydrogen chloride in alkali chloride melts (LiCl, 3LiCl-2KCl, NaCl-KCl and NaCl-2CsCl) has been studied between 450 and 750 degrees C, and the reaction products were characterized by electronic absorption and X-ray absorption spectroscopy. Uranium(V), {[}UO2Cl4](3-), and uranium(IV), {[}UCl6](2-), species were formed. They depended upon the temperature and the radius of the alkali cations present. Uranium(V) ions predominated in melts with small cations (LiCl and 3LiCl-2KCl).
