Abstract:

The Na–Cu and Na–K systems present a big interest for the study due to the use of liquid sodium and melt of sodium and potassium in the nuclear industry as a coolant in nuclear reactors. In the present work, thermodynamic modeling of phase equilibria in the Na–Cu and Na–K systems is carried out, based on the available published experimental data. This modeling was done using the “FactSage” software package (version 7.0). The set of Redlich–Kister equation parameters was obtained, that allows to describe the dependence of Gibbs energy from composition and temperature for solutions that can be formed in the studied systems. Phase diagrams (T–x diagrams) of the investigated systems were calculated.
