Abstract Scope |
MgCl2·6H2O is a phase change material with outstanding heat storage performance. To explore the potential of MgCl2·6H2O forming binary phase change materials with other substances, this study focuses on five binary phase change materials composed of magnesium chloride hexahydrate and various inorganic hydrated salts. The eutectic point composition of these binary mixtures was calculated theoretically, and their thermal storage performance was studied experimentally. The experimental results show that a binary mixture of MgCl2·6H2O and NH4Al(SO4)2·12H2O with a mass ratio of 2.61:7.39 is suitable as a binary phase change material. In this proportion, the phase change temperature of the MgCl2·6H2O and NH4Al(SO4)2·12H2O binary phase change materials is 64.3°C, and its phase change enthalpy is 208J/g. After 200 thermal cycles, the phase change enthalpy was found to be 182.24J/g. This study provides new options for developing binary phase change materials based on magnesium chloride hexahydrate. |
