Reduction of Rare Earth Elements Through Electrochemical and Metallothermic Methods
摘要
An overview of the reduction of rare earth elements through metallothermic and electrochemical methods is presented. The basic thermodynamic considerations are discussed. Metallothermic methods are reviewed, including lanthanothermy. Industrial considerations and production of rare earth metals by electrochemistry are addressed, as well as alternatives for rare earth electrodeposition. Lastly, some of the environmental concerns are described.
