Thermodynamic assessment of the ternary AgNO3–LiNO3–NaNO3 system

Based on the available experimental information, the AgNO3–LiNO3–NaNO3 ternary system and its low order AgNO3–LiNO3, AgNO3–NaNO3 and LiNO3–NaNO3 binary systems are thermodynamically assessed using the Calphad method. A set of parameters describing the Gibbs energies of the different phases is presented. Ternary parameters are necessary to describe the liquid phase in a neutral species model where each nitrate is treated as a constituent. Calculated phase diagrams and thermodynamical functions for the three limiting binary systems show good agreement with experimental data. In the ternary AgNO3–LiNO3–NaNO3 system we have calculated two vertical sections which are in reasonable agreement with the reported experimental data. Also, several isothermal sections are calculated.
