Abstract
A reversible liquid/solid phase change composition for the storage of energy comprising a mixture of hydrated calcium bromide/calcium chloride and a modifier selected from KBr, KCl, or mixtures thereof, for modifying the semicongruent melting of the mixture to reduce the formation of crystalline CaBr.sub.2 and CaCl.sub.2 hydrate phases other than the hexahydrate phase. The composition is useful over a temperature range of from about 5.degree. to about 50.degree. 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.
