Thermodynamic Properties of Molten Mixtures of Cerium Chloride and Calcium Chloride

The thermodynamic properties of solutions of CeCl₃ in CaCl₂ were determined by emf measurements over the concentration range unity to 10⁻³ mole fraction and the temperature range 800 to 925 deg C. The solutions behaved nearly ideally under all conditions with small deviations, if any, in the positive direction. The solvent effect on the activity of the solute cation was found to depend on the "charge density" of the solvent cation in a manner consistent with previous work. (auth)
