| Abstract Scope |
Iron-silicon-aluminum soft magnetic alloy has good electrical, mechanical and oxidation properties, and is widely used in the electromagnetic field. In this paper, Fe2O3, Al2O3 and SiO2 were used as raw materials to prepare Fe-Si-Al intermetallic compounds by molten salt electro-deoxidation process at 800°C in a NaCl-CaCl2 molten salt system. The thermodynamics of the reduction preparation process were calculated to determine the reaction process. The results show that Fe2O3 preferentially undergoes electrolytic deoxygenation, and the O2- produced by deoxidation spontaneously reacts with Ca2+ in molten salt and Al2O3 and SiO2 in the cathode to form CaAl12O19 and CaSiO3. CaSiO3 was reduced to elemental elements before CaAl12O19 and formed Fe-Si-Al intermetallic compounds with Fe. |
