Heat capacity of MgCl2·6H2O was determined in temperature range from 298.15 to 401.15 K. Polynomial function was used to fit temperature dependence of heat capacity up to 371.15 K and corresponding thermodynamic functions (HT − H298.15, ST − S298.15, GT − G298.15) were calculated. Thermal stability test (50 heating/cooling cycles) of pure MgCl2·6H2O shows supercooling about 37 K, thus some nucleating agents were tested. Addition of SrCO3 (1 wt%) and Sr(OH)2 (0.5 wt%) almost fully suppresses the supercooling while addition of Mg(OH)2 decreases supercooling by 19 K.
► We measured heat capacity of magnesium chloride hexahydrate. ► Thermal stability of magnesium chloride hexahydrate was tested using DSC. ► Some nucleating agents were applied to suppress supercooling in magnesium chloride hexahydrate.
