The Resistivity And Thermoelectric-Power Of Liquid Ag-Pd Alloys

The resistivity (?) and the thermoelectric power (S) have been measured as functions of concentration and temperature for the liquid alloy system Ag-Pd. Comparison is made between the experimental results and the theoretical predictions of a nearly free electron model adapted for liquid transition metals. It is concluded that such a theory is unable to reproduce the gross features of the concentration dependence of ? and S even when concentration-dependent effective valencies are introduced. The close similarity between the concentration dependence of the resistivity and the thermoelectric power of solid Ag-Pd alloys at high temperatures and that of the liquid alloys lends support to the alternative s-d scattering model proposed by Mott.
