Correlation between bulk and surface properties in Rb-Pb liquid alloy

Correlation between bulk thermodynamic properties and surface properties in Rb-Pb liquid alloys has been studied using a statistical model based on compound formation. This study shows that the compound formation in the bulk resulted in an increased surface tension values. A reduced surface concentration of rubidium atoms was also observed. The surface concentration fluctuation at the long wavelength limit Sccs(0) indicates tendency to a regular mixing of alloy components on the surface at high bulk concentrations of Rb.
