Scale-Up Study of Molten Salt Electrolysis using Cu or Ag Cathode and Vacuum Distillation for the Production of High-Purity Mg Metal from MgO
Autor: Toru H. Okabe, Young-Min Kim, Hyeong-Jun Jeoung, Jin-Young Lee, Tae-Hyuk Lee, Kyung-Woo Yi, Jungshin Kang, Dong Hee Lee
Publikováno v: Journal of Sustainable Metallurgy. 7:883-897
To produce high-purity Mg metal directly from MgO, the scale-up of a novel electrolytic process using a metal cathode and vacuum distillation was investigated. The electrolysis of MgO was conducted in MgF2–LiF molten salt using Cu or Ag cathode and
