Density and electrical conductivity of molten NaCl-KCl-AlCl3 mixtures

The density and specific electrical conductivity were investigated for molten ternary NaCl--KCl--AlCl3 mixtures of interest to new industrial processes for electrolytic Al 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 # < plus/minus 1.5% for the density and plus /minus 5% for the electrical conductivity, respectively.11 refs.--AA
