Fusible alloys, and gallium-based liquid metal alloys (Ga-LMA) in particular, have applications in soft robotics, microelectronics, self-healing battery components, and 2D materials synthesis, making the study of their thermodynamic properties critical to improvement and development of hybrid materials. To determine the enthalpies of formation/mixing of the binary Ga-In, the ternary Ga-In-Sn, and the quaternary Ga-In-Sn-Zn eutectics, a novel experimental calorimetric technique based on oxidative solution calorimetry was developed. The experimental results for the binary alloy are consistent with previous data obtained by direct reaction and solution calorimetry, demonstrating the viability and precision of the experimental technique, which is applicable to a large variety system that are liquid at or below room temperature. The heats of mixing in the ternary and quaternary systems represent the first reported experimental values. Both the standard geometrical models and FactSage were used to define enthalpy analogs for these systems which agreed with the experimental data, providing a foundation to analyze the thermodynamics of other unknown Ga-based alloys.
