Electrochemical Metallization of Solid Terbium Oxide

摘要

Heavy rare-earth (HRE) metals function very efficiently in advanced materials for magnetooptical-information storage,giant magnetostrictive energy conversion,and high-strength permanent magnets.A 7% annual growth in global demand for rare-earth (RE) metals was recently predicted.Although the separation of mixed RE compounds has been greatly refined,extraction of pure RE metals,especially the heavy ones,remains a historical challenge.
