Electrical Conductivity of Low-Melting AlF<sub>3</sub>-NaF and KF-AlF<sub>3</sub> Solutions
View through CrossRef
In this work the electrical conductivity of molten sodium cryolite solutions (Na3AlF6) and potassium cryolite solutions (K3AlF6) containing different contents of aluminum fluoride were investigated. Experiments were carried out in a temperature range including the liquid phase, using electrochemical impedance spectroscopy (EIS). Based on the conducted studies, it was found that the electrical conductivity of the studied electrolytes decreases with decreasing temperature and increasing content of aluminum fluoride. It was also found that in the temperature range in which the studied salts are in the liquid state, the solutions of potassium cryolite have lower electrical conductivity than the solutions of sodium cryolite.
