Abstract:The equilibrium data on the ternary system of NH4Cl-CaCl2-H2O at 25℃, 50℃ and 75℃ were investigated using the wet-residue method. The experimental results show that there are two pure phase crystal areas of NH4Cl and CaCl2•6H2O and their mixture phase crystal areas at 25℃. 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 at 50℃ and 75℃. A new hydration double salt (2NH4Cl•CaCl2•3H2O) was found in the ternary equilibrium system for the first time. | |||
