Activity of bismuth in liquid Ag-Bi-Ni alloys determined by equilibrium saturation method
Activity coefficients of Bi in liquid Ag-Bi-Ni alloys were experimentally determined by means of the equilibrium saturation method at 1173 and 1273 K. The measurements were carried out for alloy compositions along three sections of fixed Ag to Ni mole fraction ratio equal to 4/1, 3/2, and 2...

| Summary: | Activity coefficients of Bi in liquid Ag-Bi-Ni alloys were experimentally
determined by means of the equilibrium saturation method at 1173 and 1273 K.
The measurements were carried out for alloy compositions along three sections
of fixed Ag to Ni mole fraction ratio equal to 4/1, 3/2, and 2/3. The excess
Gibbs free energy of Bi was calculated basing on the experimental activity
coefficient data. The experimental activity data were compared to the values
calculated for two sets of assessed thermodynamic data. |
