| titleOfInvention | Method for preparing Mg-Nd base intermediate alloy by using neodymium iron boron waste |
| abstract | The invention discloses a method for preparing Mg-Nd base intermediate alloy by utilizing neodymium iron boron waste, belonging to the technical field of metal materials. The invention relates to a method for preparing Mg-Nd base intermediate alloy by utilizing neodymium iron boron waste, which is to add the neodymium iron boron waste into MgCl 2 In a molten salt of (2), and then making Nd of the molten salt by electrolysis 3+ 、Pr 3+ 、Dy 3+ With Mg 2+ The ions are reduced and alloyed together at the cathode to a Mg-Nd based master alloy which can be used to produce magnesium neodymium alloys, and also to prepare rare earth metals with magnesium by vacuum distillation. By adopting the technical scheme of the invention, the neodymium iron boron waste is added into MgCl 2 (or MgF) 2 Or AlCl 3 ) In the molten salt, the rare earth elements in the molten salt can be directly recovered in a Mg-Nd base intermediate alloy mode through electrolysis, and the method is simple in process, high in additional value of recovered products and high in comprehensive utilization degree, and can also be used for treating oxidized neodymium iron boron waste materials. |
