Abstract
The high-dilution diffusion coefficients of K+, Rb+, Cs+, and Tl+ in molten LiNO3-KNO3 mixtures are measured over a wide range of temperatures and concentrations by means of wavefront- shearing interferometry. A slightly positive deviation from linearity is found for the concentration dependence of the diffusion coefficient of K+ , Rb+, and Tl+, while no deviation is found for Cs+ within the experimental error. This is qualitatively discussed from the viewpoint of the ionic radii, the free space in the solvent, and the interaction between the diffusing and the surrounding ions
