摘要：

The phase diagram of the LiNO3-NaNO3-Ca(NO3)(2) ternary system was predicted by using an asymmetric Toop model. The thermogravimetry and Differential Scanning Calorimeter experiments of the predicted eutectic composition were also carried out. The eutectic temperature and composition reported in various literatures are evaluated based on the results determined in this work. The results show that the eutectic temperature and composition reported by Storonkin et al. (Vopr Termodin Geterogen Sist i, 2: 128-139, 1973) is more reliable than reported by other literatures. It is indict that wider working temperature window (lower condensation point) in solar thermal power plant can be obtained when the thermal energy storage medium of the titled system is prepared with the eutectic composition determined in this paper.
