Application of annexation principle to the study of thermodynamic properties of ternary molten salts CaCl_2-MgCl_2-NaCl

摘要

Based on the practical basis of measured activities and phase diagrams as well as in the light of the mass action law. the model of inseparable cations and anions of molten salts and mattes, and the annexation principle of two kinds of solutions in binary melts, the calculating model of mass action concentrations of molten salts CaCl_2-MgCl_2-NaCl was formulated. The results of calculation not only agree with experimental values, but also obey the mass action law, testifying that the model formulated can embody the structural characteristics of these ternary salts, and that the model of inseparable cations and anions as well as the annexation principle of two kinds of solutions in binary melts are also applicable to these ternary salts.
