Electrical Conductivity of Molten Fluoride–Chloride Electrolytes Containing K₂SiF₆ and SiO₂

The electrical conductivity of fluoride–chloride electrolytes for solar silicon electrolysis was investigated using impedance spectroscopy. Electrolytes containing potassium fluoride, potassium chloride, cesium chloride, potassium hexafluorosilicate, and silicon oxide were studied. The influence of the electrolyte composition on the electrical conductivity was examined.
