Thermodynamic properties of liquid Li-Pb, Na-Pb, and K-Pb alloys: similarities and differences

Conference ·
OSTI ID:6036617
The thermodynamic properties (e.g., activities, activity coefficients, entropies, free energies of mixing) have been determined for liquid Li-Pb, Na-Pb, and K-Pb alloys over the entire composition range. For the two latter systems, a solid electrolyte consisting of either Na-..beta..Al/sub 2/O/sub 3/ or K-..beta..Al/sub 2/O/sub 3/ was used in the electrochemical cell which was operated by a standard coulometric titration technique. The results show an unusual composition dependence of the excess chemical potential of the alkali metal. For Li-Pb and K-Pb, a single inflection point is obtained at compositions around 20 at. % and 50 at. % Pb, respectively, while three inflection points are present in the Na-Pb system at about 20, 33, and 50 at. % Pb.
