| Abstract: | The density and specific electrical conductivity were investigated for molten ternary NaCl-KCl-AlCl3 mixtures of interest to new industrial processes for electrolytic aluminium deposition. A method for the calculation of density and electrical conductivity of molten ternary mixtures on the basis of experimentally determined values for the binary systems NaCl-AlCl3, NaCl-KCl and KCl-AlCl3 has been proposed. The difference between the experimental and calculated density and electrical conductivity values of the ternary system was less than ± 1.5% for the density and ± 5% for the electrical conductivity, respectively. |
