The Electrical Resistivity of Sodium between 78 K and 372 K

Abstract

The resistivity was measured to slightly beyond the melting point and results compared with those from previous determinations. There was a small inflection in the curve of (resistivity/temperature) against temperature at about 250°K which could not be simply explained on present conductivity theories and the hypothesis that part of the high temperature resistance is due to lattice defects is considered. The measurements on solid sodium were taken to within 0.04° of the melting point and no further anomalies were found.
