The hydrate forms in the quaternary system KCl + BaCl₂ + SrCl₂ + H₂O at 323 K are the same as those of its subsystems. The quaternary phase diagram contains one invariant point, three isothermal solubility curves and three crystallization regions, where the equilibrium solid phases are KCl, BaCl₂·2H₂O and SCl₂·6H₂O.
