Density and Molar Volume of Molten GdCl3–NaCl and GdCl3–KCl Binary Mixtures

Resumo

The densities of the salt melts of the GdCl₃–NaCl and GdCl₃–KCl systems are determined by the dilatometric method over the entire concentration range and in a wide temperature range. The molar volumes of the systems and their deviations from additivity are calculated. All electrolyte composition dependences are nonlinear. The results can be used in the manufacture of gadolinium and its compounds and for the refinement of the structures of the molten salt systems under study.
