Study on Phase Equilibrium of the Ternary System of NH4Cl-CaCl2-H2O at 50C

摘要：

The phase diagram of the ternary system of NH4Cl-CaCl2-H2O is the thermodynamic guidance in the utilization of the natural salts from seawater. The equilibrium data of the ternary system of NH4Cl-CaCl2-H2O at 50℃ were investigated using wet-residue method. The experimental results show that there are three pure phase crystal areas of NH4Cl, 2NH4Cl·CaCl2·3H2O and CaCl2·2H2O, two mixture phase crystal areas of NH4Cl and 2NH4Cl·CaCl2·3H2O, and 2NH4Cl·CaCl2·3H2O and CaCl2·2H2O in the system. A new hydrated double salt (2NH4Cl·CaCl2·3H2O) was found in the ternary equilibrium system.
