(S035) Preparation of the gradient silicon steel by electrodeposition of molten salt

摘要

Silicon steel is an important soft magnetic alloy used in the electric power and electronic industries and military applications. Many researchers reported successful electrodeposition of Si4+ from fluoride melts, but the mechanism of Si4+ in the molten salt system of NaCl-NaF-KCl-SiO2 haven't been reported. In the present research, the electrochemical behaviour of Si4+ on a Fe electrode in the molten salt system of NaCl-NaF-KCl-SiO2 with various electrochemical methods were investigated; meanwhile, the phases formed on the surface of the deposit were analysed. It provides a theoretical basis for the preparation of functional materials for silicon steel.
