Abstract:  The possibility of preparation of silicon alloys by the electrolysis of silica dissolved in cryolite was studied. The data on temperature of primary crystallization, density, and specific conductivity of Na₃AlF₆—SiO₂ — AI₂O₃ mixtures, important from the aspect of the electrolysis, are presented. Furthermore, decomposition voltage of SiO₂ and AI₂O₃ under different conditions and the results on the current efficiency measurements in the electrolytic preparation of Al —Si, Cu — Si, Cu—Al, and Cu —Si —Al alloys are reported.
