Electrical Conductivity Measurement of Molten Salts Using a Two-Electrode Alternative Current Impedance Method

Abstract

The electrical conductivity of molten salts was measured at various temperatures using a two-electrode AC impedance method. The conductivity of the LiCl-KCl molten salt was 1.87 ± 0.01 S/cm at 773 K, which is the target temperature of the electrorefining process in the pyroprocess under development in Korea. The conductivity of the LiCl-KCl molten salt increased with an increase in temperature. All conductivity data in the range between 650-850 K were consistent with the data predicted by the equation proposed in the literature.
