| Abstract Scope |
Intermetallic compounds comprised of cerium (Ce), a transition metal (M), and indium (In) are of considerable interest as they possess a variety of unique physical properties, such as superconductivity. However, not every combination of cerium and indium with a transitional metal produces an interesting or useful compound. Thermodynamic modeling is useful in designing new materials as it can verify if a new phase is stable and can be synthesized. Despite the interest in the ternary systems, the thermodynamics of the Ce-In binary system is still not fully known. Thus, in this work the thermodynamic properties of Ce3In were assessed by means of high-pressure synchrotron X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, PPMS measurements, and high temperature gallium melt drop solution calorimetry. The derived thermodynamic parameters include isothermal compressibility, Cp, ΔSf, ΔHf, ΔHfus, and ΔGf. These results have been verified using either semi-empirical models or density functional theory calculations. |
