Abstract
The MgSO4–NaCl–H2O system was studied in the temperature range from –25 to 42°С by the visual polythermal method of solubility. A polythermal diagram of the solubility of this system was constructed on the basis of the solubility polytherms of binary systems and internal sections. On the phase diagram of the MgSO4–NaCl–H2O system the crystallization fields of ice, MgSO4∙H2O, MgSO4∙6H2O, MgSO4∙7H2O, MgSO4∙12H2O, NaCl∙H2O, and compound of the composition MgCl2 were delimited. The study results show that the MgSO4–NaCl–H2O system belongs to the complex eutonic type.
