| Abstract: | 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. |
