The rare-earth elements (REE), also called the rare-earth metals or rare earths or, in context, rare-earth oxides, and sometimes the lanthanides (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.
Rare earth elements (REE) are seventeen metallic elements that are essential for many high-tech devices. Learn about their origin, distribution, abundance, supply and demand, and the challenges of global production and trade from the American Geosciences Institute.
21 de abr. de 2024 · Learn about the 16 rare-earth elements, their discovery, history, and applications in various technologies. Find out why they are not so rare and where they are produced and refined.
The rare earth elements are all metals, and the group is often referred to as the "rare earth metals." These metals have many similar properties, and that often causes them to be found together in geologic deposits.
Learn about the rare earth elements, a group of metals with similar chemical properties and various applications. Find out which elements are included, how they are classified, and what they are used for.
1 de jul. de 2019 · Rare earth elements (REE) include the lanthanide series elements (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. Currently these metals have become very critical to several modern technologies ranging from cell phones and televisions to LED light bulbs and wind turbines.
