Abstract
The solubility diagram of the ternary system NdCl3–PrCl3–H2O has been studied by the method of isothermal saturation in ampules at 25°C. In the system NdCl3–PrCl3–H2O, isovalent substitution solid solutions with the miscibility gap (PrCl3)x(NdCl3)1 – x·6H2O and (PrCl3)x(NdCl3)1 – x·7H2O have been crystallized. In the system, there is one non-invariant eutonic type point, corresponding to the saturation of the solution by two solid phases.
