The thermodynamical properties of MgCl2 in KCl-MgCl2-LiCl molten electrolytes containing MgCl2 below 0.5 (mole fraction, the same below) have been determined from the interchange energies of two binary systems KCl-MgCl2 and LiCl-MgCl2, by means of a model on the assumptions that the electrolytes in the solution are treated as independent particles instead of their ion forms and the interchange energy between the component pair KCl-LiCl is ignored when compared with those of component pairs KCl-MgCl2 and MgCl2-LiCl. The interchange energies, omega(KCl-MgCl2) and omega(MgCl2-LiCl) are obtained as -70000 and -13800 J.mol(-1), from the corresponding binary solutions, respectively.
