Following up previous findings, according to which thorium, zirconium, titanium, and beryllium are dissolved in molten alkali metal chlorides under formation of either alkali metal suboxides or of alloys, the interaction of metallic bismuth with molten mixtures containing UCl/sub 4/ + NaCl, LiCl, or CaCl/ sub 2/ was investigated, including also a study of the effect of LiF and CaF/sub 2/ additions to the above mixtures. It was found that the uranium does not precipitate out on the surface of the metallic bismuth but passes into the black residue which contains 41.6 to 77.3 wt.% uranium, 2.5 to 8.5 wt.% bismuth, and 2 to 16 wt.% alkali metal. The components form an actual compound rather than a mixture of distinct phases, according to the x-ray-diffraction analysis. equivalent amount of bismuth was dissolved by the melt. The compound was found to be insoluble in the molten salt mixture or in molten bismuth. The reaction is given by the following expression: 3 U/sub 4/ + Bi - 3 U/sup 3+/+ Bi/sup 3+/. The deposit seems to hinder the formation of a U-Bi alloy. (TTT)
