AN INVESTIGATION OF THE SODIUM-POTASSIUM EQUILIBRIUM DIAGRAM

Abstract

The study of fundamental properties such as specific heat and electrical resistivity in pure metals has made it very important to know the influence of small amounts of impurity. This has led us to undertake a detailed investigation of the sodium–potassium equilibrium diagram. Previous work had indicated zero solid solubility at each limit (100% Na; 100% K) but the present investigation shows in particular that solubility extends to a few per cent from either limit.
