Electrical resistivity of liquid potassium and of solutions of sodium in liquid potassium: the potassium–sodium phase diagram

Abstract

The electrical resistivity of liquid potassium and of solutions containing up to 30 atom % sodium in liquid potassium have been determined from the liquidus to 300 °C. Equations for the variation in the resistivity of the liquid metal with temperature and with composition are given. Resistivity–temperature curves at constant composition have been extended into the solid phase to allow determination of part of the phase diagram. The resistivities and phase equilibria are compared with previously reported data.
