      abstract     = {Thermodynamic properties of the quasi binary
                      Ca(NO3)2–NaNO3 system are of interest with respect to
                      thermal energy storage. In the present work the phase
                      diagram as well as thermodynamic properties of the near
                      eutectic mixture $45 mol\%$ Ca(NO3)2 – $55 mol\%$
                      (NaNO3)2 were determined experimentally and applied in the
                      assessment of a new Gibbs energy dataset for thermochemical
                      calculations. The enthalpy of fusion of the $45 mol\%$
                      Ca(NO3)2 – $55 mol\%$ (NaNO3)2 mixture is determined to
                      be 24.7 ± 0.5 kJ/mol. The melting and crystallization
                      enthalpy have good reproducibility, which makes it possible
                      to use this mixture as a phase change material at
                      temperature 225 °C. The assessed dataset describes liquid
                      phase properties using a subregular solution model in the
                      Redlich-Kister formalism with high accuracy. Therefore it
                      can be used for the prediction of thermodynamic properties
                      of different compositions in the whole Ca(NO3)2–NaNO3
                      system and be included in databases for calculation of
                      multicomponent systems including other components.},
