Abstract

The equilibrium distributions of thorium and radium between molten LiCl-LiF salt and liquid bismuth were determined over a wide range of salt composition at 913 and 1, 023 K. The distribution behavior of thorium was apparently affected by salt composition and temperature, but that of radium was little affected. The effect of salt composition on the distribution behavior was well explained by considering the formation of complex compounds in the salt phase. The thermodynamical properties of the complex compounds were also evaluated.
