ABSTRACT:
A supercooling inhibitor comprising a supercooling inhibitor base having all or part of its surface coated with sodium acetate trihydrate. The supercooling inhibitor base comprises one or more members selected from the group consisting of sodium pyrophosphate (Na.sub.4 P.sub.2 O.sub.7), trisodium monohydrogen pyrophosphate (Na.sub.3 HP.sub.2 O.sub.7), disodium dihydrogen pyrophosphate (Na.sub.2 H.sub.2 P.sub.2 O.sub.7), monosodium trihydrogen pyrophosphate (NaH.sub.3 P.sub.2 O.sub.7), sodium pyrophosphate decahydrate (Na.sub.4 P.sub.2 O.sub.7.10H.sub.2 O), and disodium dihydrogen pyrophosphate hexahydrate (Na.sub.2 H.sub.2 P.sub.2 O.sub.7.6H.sub.2 O). The supercooling inhibitor of the present invention is useful for inhibiting the supercooling of sodium acetate trihydrate which is used as a heat regenerating material utilizing heat of fusion.
