EMF AND CALORIMETRIC MEASUREMENTS ON THE MG-IN LIQUID SOLUTIONS

By means of concentration cells: Mg (s)IMgClM2 (LiCl)KCl)eut(l)|Mg-In (l) partial molar thermodynamic data of Mg in Mg-ln liquid alloys have been determined in the composition range 0.03 ≤X Mg ≤ 0.6 and at temperatures 770 to 890 K. Integral molar enthalpies measured in a Calvet calorimeter at 948 and 1008 K were used for calculation of the partial molar enthalpy of magnesium, {Mathematical expression}. Values of {Mathematical expression} with partial molar free energies of Mg from emf studies were used for derivation of partial molar excess entropies. © 1979 American Society for Metals and the Metallurgical Society of AIME.
