| Abstract Scope |
MoAlB has attracted extensive attention owing to its excellent compressive strength, hardness, flexural strength, and fracture toughness. To achieve low-cost and green synthesis of MoAlB, the theoretical feasibility of preparing MoAlB by using molten salt electrochemical method with MoO3, Al2O3, and B2O3 was analyzed. The results indicated that within 0–1200 °C, Al2O3 and B2O3 could react to form intermediate products Al4B2O9 and Al18B4O33. NaCl and CaCl2 had no react with raw materials. Under the conditions of 700−1000 °C and a decomposition voltage of −2.64 V to −3.12 V, the raw materials and intermediates could be electrolyzed to Mo, B, and Al, then alloyed to form MoAlB. Based on the above thermodynamic conditions, the feasibility of several reaction pathways for the preparation of MoAlB by the molten salt electrochemical method was theoretically predicted. Mo and Al form Al8Mo3.Mo and B form MoxBy. Al and B form AlB2, yielding MoAlB. |
