Abstract
A reversible liquid/solid phase change composition comprising a mixture of hydrated CaCl.sub.2 and KCl in which the KCl modifies the semi-congruently melting behavior of CaCl.sub.2.6H.sub.2 O to the extent that the mixture approaches congruent melting behavior. The composition preferably includes nucleating additives to modify and suppress the supercooling properties of the liquid phase of the composition. The composition most preferably comprises an admixture of hydrated CaCl.sub.2 and KCl having an amount of NaCl and/or SrCl.sub.2.6H.sub.2 O as an additive sufficient to obtain an effectively congruently melting mixture.
