abstract = {Thermodynamic properties of calcium nitrate are of interest
for development of thermodynamic databases, which can be
applicable for thermal energy storage technologies. In the
present work thermodynamic properties of Ca(NO3)2, i.e. heat
capacity (Cp) and enthalpy of fusion, were determined
experimentally. The enthalpy of fusion of Ca(NO3)2
(33.4 ± 1 kJ/mol) was measured in a closed
Pt-crucible at the melting temperature 823 K for the first
time. The heat capacity of Ca(NO3)2 was measured in the
temperature range from 143 K to 723 K by three different
differential scanning calorimeters. High temperature X-ray
diffraction was used for determination of the temperature
dependence of volume from 298 K to 723 K. Combination of
heat capacity and volume allowed us to calculate the molar
volume at 0 K and to obtain the thermal expansion. The
Grüneisen parameter and bulk modulus were deduced from
combination of the available ab initio values of Cv and the
values of Cp as well as the thermal expansion obtained in
this work. This methodology allowed us to perform a
comprehensive analysis of experimental values and first
principal calculations. A complete thermodynamic dataset for
solid and liquid Ca(NO3)2 has been derived. Previous article
