Electrochemical Synthesis of Magnetic Materials Based on Intermetallic and Refractory Compounds of Rare-Earth Metals in Ionic Melts: Current State of Research and Directions of Development

This review focuses on the electrochemical synthesis of intermetallic and refractory compounds in ionic melts using rare-earth metals, the iron triad, boron, and silicon. The widespread usage of rare earth metal-based magnets with record-high magnetic properties is impeded by their expensive cost, difficult manufacturing techniques, and the presence of rare metals. In chloride and chloride-fluoride melts, data on the electrochemical behaviour of lanthanides, iron, cobalt, and nickel chloride complexes, as well as fluoroborate and fluorosilicate ions are provided. Distinctive Characteristics of The electroreduction of rare-earth metal ions with iron triad ions, fluoroborate, and fluorosilicate ions is investigated. The ideal conditions for the electrosynthesis of rare-earth metal-based double and triple molecules are discussed. Future prospects for high-temperature rare-earth metal electrochemistry and technical solutions in the realm of electrosynthesis of rare-earth metal compounds in molten salts are discussed.
