Resistivity of Liquid Sodium-Cesium Alloys up to 300°C

Abstract

For a number of liquid sodium-cesium alloys the electrical resistivity $\rho$ has been measured as a function of temperature $T$ in the range 50-300°C. As a function of the cesium concentration $c$, ${\left(\frac{\partial \rho }{\partial T}\right)}_p$ exhibits a distinct minimum for $c=0.6\mathrm{}$, which gradually disappears at higher temperatures. This minimum is related to the results for the resistivity at high pressure recently obtained by Tamaki, Ross, Cusack, and Endo.
