The Variational Calculation of Bulk Moduli for Liquid Binary Alloys of Alkali Metals

Abstract

The bulk moduli of the Na-K, Na-Cs, and K-Rb liquid equiatomic alloys at T = 373 K are calculated by the variational method with the hard-sphere reference system. The local Animalu-Heine model pseudopotential and Toigo-Woodruff exchange-correlation function are used for the calculation. A good agreement with experimental data is achieved.
