Self-diffusion and electrical conductance measurements on solutions of cadmium in molten cadmium chloride

An apparatus designed for manipulations involving volatile materials at high temperatures, has been used to measure the diffusion coefficients of cadmium and chlorine in solutions of cadmium in molten cadmium chloride by the open capillary technique. Measurements of electrical conductance and solubility have also been made. The results are interpreted in terms of the effect of structural changes in the melts on the ionic diffusivities and are shown to be in accord with a model involving partial "association" to CdCl⁺ and Cd₂Cl⁺ ions.
