The Pressure of Saturated Vapors of Liquid Alloys of Alkali Metals at High Temperatures: Na–Rb System

Abstract

The pressure of saturated vapors of a molten Na–Rb system is calculated from the experimental data on the activity coefficients of the components of this system at temperatures of 773 and 1073 K in a wide range of its compositions available in the literature [1, 2]. The calculated values of the saturation pressure of liquid sodium–rubidium alloys are compared with the results of an experimental investigation of the ps–Ts dependence for a Na–Rb alloy containing 60.78 at. % Rb [3].
