The heat capacity at constant pressure in the nearly-free-electron approximation for binary liquid alloys of alkali metals

摘要

The heat capacity at constant pressure is calculated within the nearly free-electron approximation by the Variational method with the hard-sphere reference system for Na-K. Na-Rb and K-Rb equiatomic liquid alloys at T - 373 K. A good agreement with experiment for Na-K alloy is achieved. Results obtained for Na-Rb and K-Rb alloys may be considered as a prediction.
