Abstract
The lithium activity in Li−LiCl solutions has been measured by means of potentiometry in the salt-rich region of the phase diagram. The results showed that, at temperatures up to 200°C above the melting point of LiCl, the solubility of Li was several atom-percent (from 1 to 5%), as in the case of the other alkali metals dissolved in their molten halides. But the Li−LiCl system differs from the other alkali metal-alkali halide systems in that the metal activity in the saturated solutions does not exceed 0.1. This indicates the possible formation of a stable compound by the association of Li and LiCl.
