The aim is to understand the thermodynamic behavior of SmF3 with various fluoride salts for advanced energy applications.
Developed Gibbs energy functions using a modified quasi-chemical model in quadruplet approximation.
Conducted differential scanning calorimetry and X-ray diffraction experiments to establish phase equilibria in mixed salts.
Estimated enthalpies of mixing based on ionic size difference parameter.
Confirmed thermodynamic instability of the LiSmF4 phase and determined melting temperatures of K3SmF6.
Measured low-temperature heat capacities of NaSmF4, KSmF4, and K2SmF5 for the first time.
Provided a validated thermochemical description for predicting Sm-bearing phase stability in FLiNaK salts.
