In Situ X-ray Diffraction and Crystal Orientation Analysis for Dy–Ni Electrochemical Alloying and De-alloying in Molten LiCl–KCl–DyCl3
Autor: Yumi KATASHO, Tetsuo OISHI
Publikováno v: Electrochemistry, Vol 92, Iss 4, Pp 043004-043004 (2024)
In situ white X-ray diffraction was used to investigate the electrochemical alloying and de-alloying processes of Dy–Ni alloys in molten LiCl–KCl–DyCl3 at 723 K. X-ray diffraction peaks of Ni and DyNi2 and fluorescence peaks of Dy were obtained

Permeation Tendency of Rare-earth Elements through a Ni-based Alloy Diaphragm in LiCl–KCl Eutectic Melts
Autor: Tetsuo OISHI, Miki YAGUCHI, Yumi KATASHO, Hirokazu KONISHI
Publikováno v: Electrochemistry, Vol 92, Iss 4, Pp 043016-043016 (2024)
The permeation tendency of La, Ce, Pr, Nd, Gd, and Tb was examined using a rare earth (RE)–Ni alloy diaphragm in LiCl–KCl eutectic melts at 450 °C. This experiment was conducted as a part of an ongoing study on a new recycling process for Nd–F

In situ X-ray diffraction analysis of electrochemical Dy–Ni alloying in molten LiCl–KCl
Autor: Yumi Katasho, Tetsuo Oishi
Publikováno v: Electrochemistry Communications, Vol 138, Iss , Pp 107287- (2022)
In situ energy-dispersive X-ray diffraction was employed to investigate electrochemical Dy–Ni alloying in molten LiCl–KCl at 723 K. This enabled the determination of the crystal structures and orientations of the products formed during molten sal

Electrochemical Formation of Dy-Ni Alloys in a Molten Cesium Chloride System
Autor: Hirokazu Konishi, Tatsuya Takao, Tetsuo Oishi, Toshiyuki Nohira, Yuichiro Koizumi
Publikováno v: ECS Transactions. 109:3-9
Dy-added Nd-Fe-B magnets are widely used for high-performance motors in battery electric vehicles (BEVs), hybrid electric vehicles (HEVs) and so on. The demand for these magnets is increasing due to the spread of BEVs and HEVs. However, Dy resources

Electrochemical Reduction Behavior of Boron in Molten LiCl–KCl–KBF4
Autor: Yumi Katasho, Tetsuo Oishi
Publikováno v: ECS Transactions. 98:53-59
1. Introduction The consumption and demand of Nd-Fe-B magnets, so-called neodymium magnets, is increasing year by year. Since the rare earth elements such as Nd can be obtained from sparse mineral resources, the technology for the recycling system of

Selective Permeation of Neodymium Through an Alloy Diaphragm in Molten Chloride Systems
Autor: Yumi Katasho, Miki Yaguchi, Tetsuo Oishi, Toshiyuki Nohira
Publikováno v: ECS Transactions. 98:27-32
The authors have been investigating a new RE (RE=Dy and Nd) recycling process from Nd-Fe-B permanent magnets, which is characterized by the use of RE-IG (IG=Fe, Ni, Co) alloy diaphragms for separation of REs in molten salts (Fig. 1) [1, 2]. In this p
