Investigation on Preparation of Fe-Al Alloys by Direct Reduction of Fe2O3-Al2O3 Powder in CaCl2-NaCl Molten Salt System: Jinrui Liu¹; Hui Li¹; Jinglong Liang¹; ¹North China University of Science and Technology
    Fe-Al Alloys has been synthesized directly from Fe2O3-Al2O3 powder by electro-deoxidation in the CaCl2-NaCl molten salt at 800 °C. The thermodynamic decomposition voltages of Fe2O3, Al2O3 and compounds in molten salt to their corresponding metal in 800 °C has been analyzed. Constant voltage electrolysis has been utilized to investigate the formation process of Fe-Al Alloys. The results indicated that Fe2O3 is decomposed into Fe earlier. It is found that with the first reduction product Fe, the later reduction product Al will immediately form Fe3Al and FeAl which are more refractory, avoiding the loss of Al due to its low melting point thereby.
