Abstract:  The system Na3AlF6 —SiO2 — AI2O3 —AlF3 was studied with regard to the possibility of a one-step production of Al—Si alloy by the electrolysis of the cryolite-based melts. It was found that in the above system the components react and SiF4 is formed. The dependence of the SiO2 losses on the melt composition and on the interaction of silica and alumina in a cryolite melt is discussed.
