PURPOSE:To provide a heat-accumulating material exhibiting a stable performance to a long period thermal cyclization by adding barium or calcium hydrogen phosphate as a nucleating agent to sodium acetate.trihydrate to reduce the extent of supercooling when solidified. CONSTITUTION:Sodium acetate.trihydrate is mixed with barium or calcium hydrogen phosphate (anhydride or dihydrate) as a nucleating agent in an amount of approximately 0.1-20wt.% (preferably approximately 0.5-10wt.%) to provide the objective heat-accumulating agent. |
