Thermodynamic modeling of the Ca-Ni system

An interest in the binary Ca-Ni system has occurred due to the possibility of using this alloy system in hydrogen storage for fuel cell applications. A coherent database of thermodynamic properties pertaining to Ca-Ni will allow for easy access to a myriad of information. Using the published phase diagram and thermodynamic data of Ca-Ni from different sources, an optimized thermodynamic model is obtained. The model provides a means for a variety of other thermodynamic properties, for which no experimental data exists, to be predicted. The Ca-Ni binary system is essential in any further development of ternary or higher order systems based on these elements. Consistency between calculated and published experimental thermodynamic values enforces the legitimacy of the findings.
