Calorimetric and phase diagram studies of the Ga-In-Zn system

Abstract Partial and integral enthalpies of mixing of liquid Ga-In-Zn alloys at a temperature of 720 K were measured by high-temperature drop calorimetry. Calorimetric measurements were performed along four intersections as follows: xGa/xZn = 3/1, xGa/xZn = 1/1, xGa/xZn = 1/3 and xGa/xIn =1/3. Based on obtained thermodynamic results and those available in the literature the thermodynamic optimization was done using Thermo-Calc software. Next, the phase equilibria in the binary and ternary systems were calculated and the results were compared with those obtained using different experimental techniques.
