Claims10
A composition for the storage of heat energy utilizing the heat of fusion of the composition, said composition comprising a salt-hydrate having a heat of fusion of more than about 50 BTU per pound, a nucleating agent and a porous solid selected from the group consisting of calcium sulfate hemihydrate and soluble calcium sulfate anhydride at a level from about 15 to about 75 percent by weight based on the weight of the salt portion of said salt-hydrate.
A method of preparing a composition for the storage of heat energy comprising the steps of forming a blend of a salt hydrate, a porous solid selected from the group consisting of calcium sulfate hemihydrate and soluble calcium sulfate anhydride at a level of from about 15 to about 75 percent by weight based on the weight of the salt portion of said salt-hydrate, and a nucleating agent, mixing water with said blend and agitating said blend until said blend solidifies.
