Abstract
The diffusion coefficients of silver in molten lead and bismuth at infinite by high dilution were studied within the temperature ranges of 451°∼639°C and 383°∼599°C, respectively, using the capillary method and with Ag110 as the radioactive tracer. The obtained results can be represented by & D_Ag in Pb = (3.13±0.25)×10^-4 exp(-3430±60/RT) cm^2/sec
& D_Ag in Bi = (8.19±0.79)×10^-4 exp(-4100±60/RT) cm^2/sec The relationship between diffusion and viscosity proposed by Einstein, Sutherland, Eyring, Li and Chang and Longuet-Higgins and Pople were tested by the obtained experimental results. It was found that the values calculated by the Sutherland, Longuet-Higgins and Pople’s equations showed good agreement with the experimental data, and hence these equations are adequate for these liquid metallic solutions.
