Abstract Scope |
Fe2AlB2 as a typical representative of MAB-phase, it becomes research hotspot with its high damage tolerance and magnetothermal effect. Due to the high raw material cost and long reaction time, a new idea of preparing Fe2AlB2 powder from Fe, Al2O3 and Na2B4O7 by molten salt electrochemical method was proposed in this paper, and its theoretical feasibility was analyzed by thermodynamic study. The results showed Fe, Al2O3 and Na2B4O7 had no chemical reaction in NaCl-KCl less than 1200℃. The molar ratio of Fe, Al2O3 and Na2B4O7 was 2:0.75:0.5. The electrochemical reaction conditions for the preparation of Fe2AlB2 were obtained at 700℃~1000℃, and the theoretical decomposition voltage was -2.37V~-3.12V. B was electrolytically reduced before Al, and then Fe2AlB2 was formed by the reaction of FeB and Al with Fe. The thermodynamic calculation results indicated the preparation of Fe2AlB2 by molten salt electrochemical method was feasible in theory. |
