Diffusion coefficients of tin, antimony and silver in lead-bismuth liquid mixtures at 773 k

Abstract

Diffusion coefficients of tin, antimony and silver in lead-bismuth liquid mixtures were measured using the capillary-reservoir technique at 773 K. The observed values were comparable with the existing data in the literature. The dependency of the measured diffusion coefficients upon the composition of the solvent mixture was found to be qualitatively estimated by the extended relaxation model proposed by Harada et al., though the quantitative evaluation of the model was not possible due to the uncertainty in the self-diffusion coefficients in pure bismuth reported in the literature. © 1983, The Society of Chemical Engineers, Japan.
