Testing the Conformal Ionic Solution Theory for the Additive Ternary Molten Salt System

The conformal ionic solution theory predicts excess chemical potentials of the components in a ternary additive molten salt system, if suitable thermodynamic data on the three subsidiary binary molten salt systems are available. The excess chemical potential of AgCl in the system AgCl-LiCl-KCl has been calculated theoretically, using the published data on binary molten salt systems AgCl-LiCI, AgCl-KCl and LiCl-KCl. The calculated values are compared with the corresponding data based on emf measurements in the ternary system, and discussed with respect to the use of the theory in the thermodynamics of additive molten salt systems
