Experimental study on the thermodynamics of the Cu–Sb–Sn liquid alloys

Antimony thermodynamic activities in Cu–Sb–Sn liquid solutions have been measured by the modified isothermal isopiestic method at 1373 K. These results were coupled with literature data for binary systems Cu-Sn, Cu–Sb and Sn–Sb in order to obtain a thermodynamic description of the ternary liquid by use of the geometrical Muggianu approach.
