Thermodynamic properties of lead–sodium–antimony liquid alloys

Resumo

The thermodynamic properties of lead–sodium–antimony liquid alloys were determined by the emf method. The thermodynamic properties of the edge binary systems, sodium–lead, sodium–antimony, and lead–antimony, were analyzed. The possibility of approximately estimating the thermodynamic properties of the ternary system on the basis of data on the edge binary systems using the simplest geometric models was demonstrated. The sodium-containing alloys show significant negative deviations from the ideal behavior. All the data are given for 900 K.
