Title: Solubility products of metal sulfides in molten salts. II. Measurements and calculations for lead sulfide in the LiCl-KCl and the LiCl-LiF eutectic compositions

Abstract

The solubilities of lithium sulfide and the solubility products of lead sulfide in the LiCl-KCl and LiCl-LiF eutectic mixtures have been measured by an electrochemical titration method in the temperature range from 673 to 823 K. At 823 K, the solubility of Li/sub 2/S in the LiCl-LiF eutectic was much larger than in the LiCl-KCl eutectic (1.95 x 10/sup -2/ compared with 3.50 x 10/sup -3/). The measured solubility product of PbS in the LiCl-KCl eutectic (1.0 x 10/sup -10/ at 823 K) did not differ greatly from that in the LiCl-LiF eutectic (6.8 x 10/sup -11/ at 823 K). A priori calculations were made of the solubility products of PbS and several transition and heavy metal sulfides in the molten LiCl-KCl eutectic at 723 K. Fundamental theories of reciprocal and additive ternary molten salt solutions are used to explain the influence of the solvent on the solubilities of Li/sub 2/S and on the solubility products of PbS. The correlation of experiments with theory illustrates the utility of known theories of ionic systems in making predictions of solubilities and solubility products in ionic systems.
