Abstract: The electrical conductivity, density, and viscosity of the molten MgCl₂-CaCl₂-NaCl-KCl quaternary system have been investigated over a temperature range of 100 K in the composition range of 6-18 mass % MgCl₂. Very low temperature coefficients and smooth isotherms were obtained over the whole temperature and respectively composition range investigated. Frenkel equation was also verified, which proves that the acting forces upon the moving ions are mutually compensated in the mixtures. An optimum composition of the electrolyte for magnesium electro-winning was recommended.
