Calorimetric study of Al–Ga system using Oelsen method

The results of calorimetric study of the Al–Ga system using Oelsen method are presented in this paper. Following thermodynamic parameters were obtained: activities, activity coefficients, partial and integral molar quantities at temperature of 727 °C, and compared with available literature data. Also, the energetic of mixing in liquid alloys has been analyzed through the study of concentration fluctuation in the long-wavelength limit.
