Publication number: 20230029439Abstract: A method for recycling a rare earth magnet is described. The rare earth magnet has a film containing Ni on the surface thereof, and the method involves immersing the rare earth magnet in a stripping solution containing a derivative of nitrobenzene, ethylenediamine, and ammonia. This strips the Ni on the surface of the rare earth magnet without deteriorating the characteristics of the rare earth magnet, thereby improving its product yield.Type: ApplicationFiled: July 7, 2022Publication date: January 26, 2023Applicant: SHIN-ETSU CHEMICAL CO., LTD.Inventors: Ko WATANABE, Kazuhito AKADA, Yuta KURIBARA, Yoshiyuki HAYASHI
