Solubilities of Components in the Сa(ClO3)2•NH4Сl-H2O System

The & Scy;a(ClO3)(2)center dot NH4 & Scy;l-H2O system has been studied in its constituent binary systems and seven inner sections, and its polythermal solubility diagram has been plotted in the range of temperatures from-42.5 to 87.5 degrees & Scy;. The solubility diagram features the crystallization fields of ice; calcium chlorate hexahydrate, tetrahydrate, and dihydrate; and ammonium chloride. Three ternary points exist in the system. The system belongs to the complex eutonic type; its components retain their individuality and show good solubility in water. In the [40% & Scy;a(ClO3)(2) + 60% H2O]-[NH4 & Scy;l] section of the studied system, variations in crystallization temperature, viscosity, density, pH, and refractive indices of the solution have been determined. The thus-obtained results have been used to plot the composition-property diagram of the [40% & Scy;a(ClO3)(2) + 60% H2O]-[NH4 & Scy;l] section of the & Scy;a(ClO3)(2)center dot NH4 & Scy;l-H2O system.
