Abstract

Abstract: Phase equilibria in the Ag–Ga–Sn ternary system have been studied experimentally by using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). Three vertical sections (Ag–Ga50 Sn50, Ga–Ag50 Sn50 and Sn–Ag50 Ga50 ) and one isothermal section at 100 °C were experimentally established. Based on available information in the literature and present experimental results, a thermodynamic description of the ternary Ag-Ga-Sn system has been developed by using CALPHAD method. Reasonable agreement between experimental data and the calculated phase diagrams is reached. The liquid projection and invariant equilibria have been calculated by using presently obtained thermodynamic parameters. Highlights: Three vertical sections were experimentally examined by DTA. Samples from isothermal section at 100 °C were examined with SEM-EDS and XRD.. Thermodynamic optimization of Ag-Ga-Sn system was performed. Liquidus surface projection and invariant reaction were calculated.
