Solubility of components in the systems MgCl2–CaCl2–H2O and (48.2% CaCl2 + 51.8% MgCl2)–NaClO3–H2O

The solubility in the systems calcium chloride–magnesium chloride–water and (48.2% calcium chloride + 51.8% magnesium chloride)–sodium chlorate–water was studied by the visual–polythermal method. Their polythermal solubility diagrams were constructed. It was determined that most of the solubility diagram of the CaCl2–MgCl2–H2O system is occupied by the crystallization field of the binary salt 2MgCl2 ∙ CaCl2 ∙ 12H2O. In the solubility diagram of the system comprising calcium and magnesium chlorides, sodium chlorate, and water, there are crystallization fields of ice, MgCl2 ∙ 12H2O, NaClO3, and also NaCl forming by the interaction between phases in the system. The formation of NaCl was confirmed by chemical and physicochemical analysis methods.
