Densities of LaCl3-alkali chlorides binary melts have been measured by the manometric method over the range of their liquidus temperatures to about 1200 K. The results obtained are summarized as follows:<BR>Density measured decreases with an increase in the content of alkali chloride for all the binary melts. Composition dependence of density shows a non-linear relation and the densities of mixtures at arbitrary compositions do not change in the order of the radius of alkali cation. Molar volume increases with an increase in the radius of alkali cation in the entire range of composition for all the binary melts. The molar volume of all the binary melt shows positive deviations from the additivity except the melt containing LiCl. The deviations become larger as the radius of alkali cation increases, and show a maximum at 50-60 mol% alkali chloride. Partial molar volumes of LaCl3 in each of the binary melts increase with increasing content of alkali chloride in the range of more than 40-50 mol% alkali chloride except the melt containing LiCl, and this tendency becomes stronger in the order of cationic radius. Expansion coefficient increases monotonically with increasing content of alkali chloride for all the binary melts and the value becomes larger in the order of cationic radius. It is found that the complex ions of LaCl4− and LaCl63− are co-existing in the melt containing LaCl3.
