Abstract: The electric conductivity of solid solutions NaAlF₆-Al₂O₃-Al has been measured in the temperature range 773-1123 K. It has been found that the conductivity increases with the increasing concentration of dissolved aluminium. A substantial increase in the electronic conductivity component with temperature has been observed. On the basis of the dependence of the electronic conductivity on AlF₃ concentration it has been concluded that the reaction of aluminium with cryolite results in the formation of metallic sodium which acts as an electron donor.
