The densities of molten NaCl-CsCl, NaCl-RbCl and LiCl-NaCl systems were measured by the hydrostatic weighing method over the entire concentration range. The molar volumes and their deviations from additivity at 800 and 850C were calculated from the experimental data. In all melts, the deviations of molar volumes from the ideal were positive, with the greatest deviations observed in melts containing from 0 to 75 of the cations having the greatest ionic moments. This is evidence that the second coordination sphere plays the principal part in breaking up the structures of these melts.
