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.
