摘要

在 -7.0°С 至 42.0°С 的温度范围内，采用目视聚热法研究了 ZnSO4 - KNO3 - H2O 体系中各组分的溶解度。相图划分了冰结晶、KNO3、K2SO4-ZnSO4-6H2O 和 ZnSO4 的领域。构建了溶解度图，并分离出一种新化合物 K2SO4-ZnSO4-6H2O。通过化学分析、X 射线相分析、热重分析和红外光谱分析，确定了这种新化合物。

STUDYING THE SOLUBILITY OF THE SYSTEM ZnSO4 - KNO3 - H2O

The solubility of the components in the ZnSO4 - KNO3 - H2O system was studied by the visual-polythermal method in the temperature range from -7.0°С to 42.0°С. The phase diagram delimits the fields of ice crystallization, KNO3, K2SO4·ZnSO4·6H2O, and ZnSO4. A solubility diagram was constructed, and a new compound K2SO4·ZnSO4·6H2O was separated. The new compound was identified by chemical, X-ray phase, thermogravimetric, and IR spectroscopic analysis.
