Abstract

The absorption spectrum of UOCl₂in molten KCl-MgCl₂salts has been measured and compared with that of the related UC1₄ spectrum at temperatures up to 932°C and melt compositions of 60–40, 34–66, and 0–100 mol %, respectively, KC1-MgCl₂. The species UOCl₂is an important intermediate in the conversion of UO₂to UC1₄ and its spectrum provides a means of monitoring the reaction, and other similar reactions, in situ. The solubility of UOCl₂has been determined from absorption spectra and has been found to be 10 to 25 times higher than reported earlier with mole fractions as high as 0.0019 in pure MgCl₂at 932°C.
