Conductivity and density data have been obtained for the system silver chloride – silver nitrate. The Arrhenius activation energy for electrical migration in molten silver chloride is constant at 1280 cal. mole−1 from 460 to 530 °C.; for silver nitrate there is a variation from 3300 cal. mole−1 at 220 ° to 2700 at 320 °C., which indicates a diminution of structural forces in molten silver nitrate with increase in temperature. The activation energy for binary melts of the two salts at 320 °C. is constant at 2700 cal. mole−1 from 0 to 20 mole % silver chloride; Frenkel's simple equation for the dependence of the activation energy on composition is not supported by this work.

Main Influence

The electrical conductivity of the molten salts of Na3AlF6-LiF-Sc2O3 system with different compositions was measured at different temperatures by the continuously varying cell constant technique. The main influence factors on electrical conductivity were analyzed. Experiment results showed that the technique of the electrical conductivity measurement is accurate and reliable and the result’s relative error is just 0.67% in comparison with those in relevant literature. With temperature rising, electrolyte conductivity increases at a rate of about 0.03S/cm for 1°C. And we also found that the conductivity increases slightly with the addition of lithium fluoride and adding scandium oxide makes the conductivity decrease slightly and more addition doesn’t cause significant effect. It was proved that the technique can measure accurately the electrical conductivity of aluminium electrolyte and other high-temperature molten salts.

Electrical conductivity is one of the most important physico-chemical parameters in chemical engineering as well as in the technology of many industrial process. Especially in the metals production by the electrolysis from molten salts or metals recovery from slags in the electric furnaces, where the great energy is needed.In this work the continuously varying cell constant (CVCC) technique for measuring conductivity of non-ferrous slags and molten salts was used. This is high-accuracy technique, which requires no calibration. The technique was verified by measuring conductivity of standard KCl solution and molten KCl. A good agreement was obtained between measured and commonly accepted literature values. The results of measured conductivity of KF-AlF3 melts were compared with data obtained by other authors. It was proved that CVCC technique can measure accurately the electrical conductivity of high-temperature molten salts and metallurgical slags.
