SOLUBILITY IN QUATERNARY SYSTEM С60(ОН)24 – NdCl3 – PrCl3 – H2O AT 25°С

Abstract

The solubility diagram of the quaternary system С60(ОН)24 – NdCl3 – PrCl3 – H2O and its ternary subsystems at 25°C was studied by the method of isothermal saturation in ampoules. In systems С60(ОН)24 – NdCl3 – PrCl3 – H2O and NdCl3 – PrCl3 – H2O isovalent substitution solid solutions crystallize with the miscibility gap (PrCl3)х(NdCl3)1-х•6H2O and (PrCl3)х(NdCl3)1-х•7H2O. In all systems there is one non-invariant point of the eutonic type corresponding to the saturation of the solution with two solid phases in the ternary subsystems and three solid phases in the quaternary system
