Reaction of Oxygen with Uranium Trichloride in Molten Alkali Metal Chlorides
Tóm tắt
The reactions of oxygen and oxygen-containing gas mixtures (Ar–O2, O2–H2O, and Ar–O2–H2O of various composition) with chloride melts containing uranium(III) ions are studied. Experiments are carried out in molten LiCl at 750°C and a LiCl–KCl eutectic mixture at 550 and 750°C. The uranium content in the melts was varied in the range 0.3–3.5 wt %. The effects of the oxygen to uranium molar ratio and the gas phase composition on the degree of precipitation of uranium from the melt and the composition of the formed products are studied.
