A reversible liquid/solid phase change composition for the storage of energy comprising a mixture of hydrated calcium bromide (CaBr2.6H2O), hydrated calcium chloride (CaCl2.6H2O), and a modifier selected from KBr, KCl, or mixtures thereof, for modifying the semicongruent melting of the mixture to reduce the formation of crystalline CaBr2 and CaCl2 hydrate phases other than the hexahydrate phase. The composition is useful over a temperature range of from 7 DEG to 50 DEG C and can be employed for the storage of coolness or heat, or as a buffer or heat sink to modulate diurnal swings in ambient temperature. |
