Abstract

Reversible liquid/solid phase change agent comprising a mixture of hydrated CaCl2 and a potassium salt, whose anion forms a substantially less soluble salt with calcium, and in which the potassium salt modifies the semicongruent melt formation of CaCl2,6H2O to such an extent that the mixture approaches the congruent molten structure. Preferred examples of such agents are CaCl2 mixed with potassium sulphate, potassium carbonate or potassium phosphate. The agent contains preferably additives forming crystal seeds for modification and suppression of the supercooling properties of the agent's liquid phase. The agent can be incorporated in an encapsulation agent for use as a heat storage device.
