✦ Synopsis

Viscosity coefficients of molten Cd-CdX1 (X = Cl, Br aad I) systems as a function of the mole fraction of dissolved cadmium have been measured at temperatures between 903 K and 1.2 T;, where T; is the melting point of the particular salt solvent. The influence of dissolved metal on the viscosities of these salts has been correlated with the free volumes of the salt solvent. The calculated radii of the supposed flow units were found to be closer to the radius of Cd* than that of Cd:'. According to the Cohen and Turnbull theory the temperature dependences of electrical conductivity and of viscosity of the molten cadmium halides lead to the radii of the electrical and viscosity transport units in these salts close to those of the corresponding anions.
