Correlation entropy and its relation to properties of simple liquid metals

Abstract

In this paper we will provide a prescription for evaluating properties of liquid metals from measured diffraction data. This is investigated for liquid alkali, noble and typical polyvalent metals near the melting point. First, we have calculated the pair and triplet correlation entropies. Then, we have calculated the self-diffusion coefficient D using the excess entropy (ion configurational entropy). By means of D, we estimate the viscosity coefficient η and the surface tension γ. Predicted values of D, η and γ are reasonable in size in comparison with available experimental data.
