Abstract[edit]

The different hydrate stages of calcium chloride are presented, as well as their behavior regarding solubility and hygroscopicity.

Hydrate stages[edit]

Sinjarite: CaCl2•2H2O
Calcium chloride tetrahydrate: CaCl2•4H2O
Antarcticite: CaCl2•6H2O

Solubility[edit]

Figure 1: Solubility of calcium chloride in water. The molality n(CaCl2•xH2O)•kg(H2O)-1 is plotted against the temperature.

Hygroscopicity[edit]

Figure 2: Deliquescence behaviour of calcium chloride in the temperature range from -45 to 80 °C. The water activity aw is plotted against the temperature.
