      abstract     = {Thermodynamic properties of MgCl2-MgSO4 and CaCl2-CaSO4
                      binary systems hold significant importance in the
                      exploration of potential phase change materials for thermal
                      energy storage applications. This study aims to elucidate
                      the phase diagrams and thermodynamic properties of the
                      eutectic mixtures within these systems, employing
                      experimental techniques such as Differential Thermal
                      Analysis (DTA) and Differential Scanning Calorimetry (DSC).
                      Through comprehensive experimental investigations, the phase
                      diagrams of the MgCl2-MgSO4 and CaCl2-CaSO4 systems were
                      meticulously delineated, revealing the eutectic compositions
                      and transition temperatures. Specifically, the eutectic
                      composition for MgCl2-MgSO4 was proposed to be 28.0 $mol\%$
                      MgSO4 with a melting temperature of 663 ± 5 °C, while for
                      the CaCl2-CaSO4 system it was found to be at 14.0 $mol\%$
                      CaSO4 and 722 ± 5 °C. Additionally, the enthalpy of fusion
                      of these eutectic mixtures was for the first time
                      determined, providing crucial insights into their thermal
                      behaviour. They are 38.2 ± 1.0 kJ/mol for the Mg-containing
                      system and 30.2 ± 0.4 kJ/mol for the Ca-containing system,
                      respectively. The experimental data obtained in this study
                      served as the foundation for the development of a new Gibbs
                      energy dataset, which is essential for conducting
                      thermodynamic calculations. The utilisation of this dataset
                      enables accurate predictions of thermodynamic properties
                      across the entire composition and temperature ranges of the
                      systems under investigation.},
