Abstract

The solubility of the components in the ZnSO₄ - NH₄NO₃ - H₂O system was studied by the visual-polythermal method in the temperature range from -19.4°С to +13.0°С. The phase diagram delimits the fields of ice crystallization, NH₄NO₃, NH₄NO₃·ZnSO₄·3H₂O, and ZnSO₄. A solubility diagram was constructed, and a new compound NH₄NO₃·ZnSO₄·3H₂O was separated. The new compound was identified by scanning electron microscopy (SEM), chemical, X-ray phase, and IR spectroscopic analysis.
