Abstract
PURPOSE: A heat-storing material that is prepared by mixing sodium thiosulfate pentahydrate with a specific amount, based on the heat-storing material, of sodium tartarate dihydrate, thus preventing supercooling, taking out an expected amount of latent heat efficiently and causing no deterioration of performance, even after repetition of heat cycles.
CONSTITUTION: 1W40wt%, based on the heat-storing composition, of sodium tartarate dihydrate is admixed to sodium thiosulfate pentahydrate and they are fused by heating to give the objective heat-storing material.
EFFECT: Even after repeated heat cycles of emitting melting heat near 40W45°C, deterioration such as phase separation is not observed. Water is unnecessary to be added and causes no reduction in the amount of stored heat.
