摘要：

Electrochemical reduction of silicon on metal electrodes in molten silicate was studied. An iron sheet was immersed in SiO2-Li2O-MgO at 1273 K, and the electrode potential was controlled for 1 h. Formation on the iron of a Si-containing layer about 10-30 mu m thick was observed after the electrolysis, depending on the potential. When a molybdenum electrode was used, alpha-MoSi2 layer about 5 mu m thick was formed on the surface. The results suggest the applicability of molten oxide electrolysis as a synthesis method of Si-containing alloy layers. (C) 2015 Elsevier B.V. All rights reserved.
