HYDRATED CALCIUM BROMIDE REVERSIBLE PHASE CHANGE COMPOSITION

摘要

A reversible liquid/solid phase change composition comprising a eutectic composition of CaBr2.6H2O and CaBr2.4H2O, having more than 5.4 but less than 6.0 moles of H2O per mole of CaBr2. The composition optionally includes additives selected from KBr and NaBr to lower the melting point of the composition. The composition optionally also includes a nucleating agent selected from Ba and Sr salts to reduce supercooling of the composition to 5.degree.C or less. 34,355-F
