Liquid-liquid structural transitions have been investigated by means of the emanation method in Fe−S, Co−S, Ni−S melts near the eutectic point. Both polythermal and isothermal conditions were used in the experiments. The superheating values were 0–300 ° above the melting temperature. In order to calculate the diffusion coefficient of220Rn in melts a model connecting the emanation level with the diffusion coefficient of radon was employed. Using the diffusion coefficient vs. viscosity relationship /the Stokes-Einstein relation/ the viscosity of melts as a function of the composition and temperature was obtained. Cluster-formation in sulphide melts was estimated theoretically, the particle number in a cluster as a function of the composition was determined, and a correlation was established between viscosity and particle number in clusters vs. composition.
