Calorimetric study and phase diagram investigation of the Au-Ga system

Abstract

The results of calorimetric study and phase equilibria investigation of the Au-Ga system, in the Ga-rich region, are presented. Calorimetric study was done using Oelsen methodology and partial and integral molar thermodynamic quantities were determined-at a temperature of 873 K. Phase equilibria investigations were done experimentally - using differential thermal analysis, light optical microscopy and scanning electron microscopy with energy-dispersive X-ray spectroscopy, and theoretically - using the CALPHAD method. Results agree well with available literature data.
