Abstract: The solubility diagram of the ternary system GdCl<subscript>3</subscript>–TbCl<subscript>3</subscript>–H<subscript>2</subscript>O is studied by means of isothermal saturation in ampules at 25°С. A continuous series of solid solutions of isovalent substitution crystallizes in the system The diagram of solubility in the three-component system GdCl<subscript>3</subscript>–TbCl<subscript>3</subscript>–H<subscript>2</subscript>O at 25°C is calculated according to the classical Pitzer model. Results from experiments agree convincingly with ones from thermodynamic modeling. [ABSTRACT FROM AUTHOR]
