The solubility of the binary system (LiNO3 + H2O) from T = 273.15 K to T = 333.15 K and solubility isotherms of the ternary system (LiCl + LiNO3 + H2O) were elaborately measured at T = 273.15 K and T = 323.15 K. These solubility data, as well as water activities in the binary systems from the literature, were treated by an empirically modified BET model. The isotherms of the ternary system (LiCl + LiNO3 + H2O) were reproduced and a complete phase diagram of the ternary system in the temperature range from 273.15 K to 323.15 K predicted. It is shown that the solubility data for the binary system (LiNO3 + H2O) measured in this work are slightly different from the literature data. Simulated results showed that the saturated salt solution of (2.8LiCl + LiNO3) is in equilibrium with the stable solid phase LiNO3(s) over the temperature range from 283.15 K to 323.15 K, other than the solid phases LiNO3 · 3H2O(s) and LiClH2O(s) as reported by Iyoki et al. [S. Iwasaki, Y. Kuriyama. T. Uemura, J. Chem. Eng. Data 38 (1993) 396–398].
