摘要：

The thermal behavior of sodium acetate trihydrate (NaAc&middot3H2O) was investigated by DTA, Q-TG and measurements of the solubility properties. The nucleation efficiency of Na4P2O7&middot10H2O for the crystallization of NaAc &middot 3H2O melts is not stable over long periods. Stratification can be ascribed to the formation of anhydrous sodium acetate in the supercooled melts. Under static heat storage conditions, NaAc&middot3H2O and Na4P2O7&middot10H2O do not exhibit stable behavior.
