| titleOfInvention | Method for producing rare earth transition metal alloy powder |
| abstract | A method for producing a rare earth transition metal alloy powder capable of suppressing oxidative degradation of an alloy surface during wet processing is provided. A first step of mixing a raw material containing a rare earth oxide powder and a transition metal powder with a predetermined ratio of at least one reducing agent selected from alkali metals, alkaline earth metals and hydrides thereof. And a second step of heating and reducing the mixture in an inert gas atmosphere to reduce and diffuse, and a wet treatment in which the obtained reaction product is thrown into the cleaning liquid to disintegrate, thereby reducing the reducing agent from the reaction product. A method for producing a rare earth transition metal alloy powder, comprising: a third step of performing acid cleaning by adding an acid and a cleaning liquid to an alloy slurry of the cleaning liquid, and then adding the cleaning liquid and removing the acid. As described above, there is provided a method for producing a rare earth transition metal alloy powder characterized by using glycol having a water content of 0 to 50% by mass defined by water / (glycol + water).
