| 摘要 | Reclaiming valuable metals from spent alloys involves energy-intensive pulverization and the sluggish dissolution rate. Herein, we propose an enhanced corrosion strategy to convert alloy scraps to oxide powders. The oxidation rate reaches similar to 1.67 mm h(-1) in molten CaCl2-NaCl-CaO at 700 degrees C because Cl- excludes passivation and enables continuous oxidation. In addition, the soluble CaO in molten CaCl2-NaCl prevents the generation of transition metal chlorides, which relieves using the expensive ion-selective membrane to eliminate the parasitic reaction. Overall, the molten salt enhanced anodic corrosion provides a green and general way to achieve the pulverization and oxidation of various alloy scraps. |
