Effective Interionic Potentials and Properties of Molten Noble and Transition Metals

Abstract

Abstract Recent X-ray diffraction data on molten noble and transition metals have been used to calculate effective interionic potentials by means of the Born-Green equation. The results on the noble metals are compared with the generalized pseudopotential calculations of Moriarty. In all cases the potentions were found to be insensitive to temperature and to have long-range oscillations. The results suggest that the effective valence number is close to unity in these molten metals, this giving reasonable values of the electrical resistivity when calculated in the framework of the usual Ziman theory. The self-diffusion coefficients, viscosities and surface tensions were calculated from the poten-tials and radial distribution functions using the kinetic theory of fluids. Adequate agreement with experimental data was obtained.
