Abstract

Measurements of the electrical resistivity, rho , and thermopower S, of high-purity liquid Ca and Sr are reported. It is found that, at the melting temperature, rho =23.0, S=15.2, and (1/ rho )(d rho /dT)=+6.1 for Ca, and rho =87.0, S=0.3, and (1/ rho )(d rho /dT)=-0.46 for Sr, where the units are mu Omega cm, mu V degrees C-1, and degrees C-1, and degrees C-1, respectively. These values are compared with recent calculations, special attention being given to the unusually large and positive value of (1/ rho )(d rho /dT) for Ca.
