英文摘要: The modified BET thermodynamic model was applied to predict phase diagram of the systems Mg(NO3)(2)-NH4NO3-H2O and LiNO3-Mg(NO3)(2)-NH4NO3-H2O from 273 K to 320 K, in which one quaternary eutectic point (its composition: 25.5% NH4NO3, 28.4% LiNO3, 13.8% Mg(NO3)(2) and 32.3% H2O center dot) with low melting temperature was found. The exothermal and endothermal behavior and DSC measurement of the predicted eutectic point were measured and the results showed that the melting temperature is 286.3 K and melting heat is 192.7 J.g(-1), and the predicted material is expected to be used for the potential low temperature phase change material.
