Abstract
Phase equilibria of the quaternary system (NaCl–KCl–SrCl2–H2O) at 288 K are studied by the isothermal dissolution equilibrium method. The liquid phase was subjected to chemical analysis, and the corresponding solid phase was identified via X-ray diffraction. The phase diagram was plotted according to the experimental data. In the system of (NaCl–KCl–SrCl2–H2O), there are one invariant point, three univariant curves and three crystallization regions. The invariant point corresponding to NaCl + KCl + SrCl2 · 6H2O + Liquid, three crystallization regions corresponding to the NaCl, KCl, SrCl2 · 6H2O. Double salt or solid solution was not formed between the three original components NaCl, KCl and SrCl2 · 6H2O that without dehydration. The crystallization field of KCl is the largest, it is also found that strontium chloride has the salting-out effect on NaCl and KCl in this quaternary system.
