The Rare-Earth Elements

Abstract

In this section, the elemental forms of rare-earth elements are iron gray to silvery lustrous metals that are typically soft, malleable, ductile, and usually reactive, especially at elevated temperatures or when finely divided. rare-earth elements are examined in terms of physical and chemical properties. This makes them essential components of diverse defense, energy, industrial, military technology, and low-carbon technologies. Furthermore, REEs are rapidly being used in magnet applications. For example, magnets produced by Neodymium-iron, the strongest known type of magnet, are used widely. Thus, their application areas vary from the electronic to glass industry. Also, information about the sources of rare-earth elements is given in this part.
