Abstract

The results of quantitative differential thermal analysis application in thermodynamic investigation of two gallium-based binary systems, Ga-Sn and Ga-Zn, are presented in this paper. Integral molar enthalpies of mixing in liquid state, as well as the activities, activity coefficients, and other partial and integral molar quantities were determined at the temperatures of 1000, 1073 and 1200 K (for Ga-Sn system) and 723 K (for Ga-Zn system). Obtained results were compared with literature data and comparison showed good agreement. Also, phase diagrams for the investigated simple eutectic systems were confirmed based on DTA curves and compared with literature.
