Thermodynamic Study and Characterization of Some Alloys in Ga-Sn-Zn System

The results of thermodynamic study and characterization of some alloys in Ga-Sn-Zn system are presented in this work. Thermodynamic study was conducted experimentally - using Oelsen calorimetry method and analytically - according to Redlich-Kister-Muggianu model and compared with available literature data. Characterization of alloys was done using differential thermal analysis and scanning electron microscopy, and obtained results were used in phase diagram defining of investigated section in Ga-Sn-Zn system.
