Mutual Diffusion in Liquid Rubidium–Bismuth Alloys

Аннотация

The mutual diffusion in rubidium–bismuth melts was investigated using a gammaray attenuation technique. The concentration dependence of the interdiffusion coefficient has two maxima in the vicinity of 25 and 50 at.% Bi. The analysis based on Darken’s relation shows that this feature is connected to a tendency for the formation of associated complexes in the liquid alloys.
