Thermodynamics of liquid Mg-Bi alloys

Abstract

Thermodynamic studies on liquid Mg-Bi alloys have been carried out using the e.m.f. method. A cell is described, suitable for measuring Mg activities in this system. Values of the excess partial molar free energy, the relative partial molar free energy, entropy, and enthalpy are listed along with the corresponding integral quantities. The results are compared with previous vapor pressure and calorimetric measurements as well as investigations of the phase diagram. Wagner's interpretation in terms of electronic constitution is consistent with the present data.
