| Outline of Final Research Achievements |
In htis work, the foundation for the process of efficiently collecting rare earth elements with high scarcity such as neodymium (Nd) and dysprosium (Dy) contained in rare earth magnets used for automobiles, air conditioners, vibrators of mobile phones, etc. was nvestigated. For the purpose of obtaining the basic data, we selected the electrodeposition which is one of the methods for obtaining a thin film at low cost.
Nd could be electrodeposited from the electrolyte consisting of dimethylsulfone (solvent) and NdCl3 (electrolytic salt). Furthermore, from the viewpoint of safety and energy cost, we used ethyl methyl sulfone (the melting point is lower than that of dimethylsulfone). The electrodeposition of Nd was possible even at 60 C by using NdCl3/ethyl methyl sulfone electrolyte.
