The use of thermal analysis and of equilibration with a new method of sampling yielded improved data for consolute temperatures and compositions as well as for the solubilities of the metul in the molten salts in the lower temperature range. The consolute compositions of 28 mole % Na (at 1180 deg C), 50 mole% Na (1080'C), 52 mole% Na (1026 deg C), and 59 mole% Na (1033 deg C) for the NaF-Na. NaCI- Na, NaBr- Na, and NaI- Na systems, respectively, reflect the influence of the relative sizes of the metal and halide constituent on the symmetry of the phase diagrams. The depression of the melting point of the salt represented by the monotectic temperature and composition of the saltrich phase corresponds to a positive deviation from Raoult's law similar to the one observed in the KX-K systems. A similar tentative interpretation, the association of the metal to diatomic molecules, is proposed. (auth)
