Thermodynamic activities of Cd were determined for the
Ce–Cd system in the temperature range between 690 and
1080 K and the composition range between 48 and 85 at%
Cd based on an isopiestic vapor pressure method.
values were converted to a common temperature of 823 K
and are given for the composition range 48–100 at% Cd. Using
a literature value of ln aCe as integration constant, it was
possible to calculate Ce activities and integral Gibbs energies
of formation for the same temperature and composition range.
A minimum of ΔGCd¼ 37 kJ g-atom1 was obtained in the
phase CeCd.
