Using the method of directed crystallization, partition coefficients have been determined for sodium, potassium, rubidium, cesium and silver in lithium chloride. A theoretical calculation of impurity partition coefficients has been made for the systems investigated with due regard for excess functions of mixing in solid solutions and melts. In the LiCl–Cs system, an abrupt jump of the CsCl partition coefficient has been detected in the range of very low CsCl concentrations in the melt. This effect is explained by the interaction of the cesium umpurity with the cation vacancies.
