<p>PROBLEM TO BE SOLVED: To provide a reaction material for a chemical heat pump in which a crystal structural change from III type calcium to II type calcium sulfate can be suppressed even in the case a heat storage-heat radiation process is repeated.SOLUTION: Provided is a reaction material for a chemical heat pump, in which a structural change is possible between a compound comprising a III type gypsum anhydride, a magnesium compound and a compound including CaMg-SOand a compound comprising hemihydrate gypsum, the hydrate of a magnesium compound and the hydrate of CaMgSO; where, x satisfies 0<x<1 by heat storage-heat radiation.</p> |
