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 yttrium and scandium, 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 ...
1. Juli 2019 · Rare-earth elements (hereinafter referred to as REE) are a group of seventeen chemical elements in the periodic table, in particular the fifteen lanthanides as well as yttrium and scandium as defined by the International Union of Pure and Applied Chemistry (IUPAC).

16. Jan. 2023 · The rare earths are the lanthanides — lutetium and all 14 elements between lanthanum and ytterbium across one row of the periodic table — plus scandium and yttrium, which tend to occur in the...
5. Jan. 2024 · Obtaining rare earth elements begins with obtaining source materials, which can happen, broadly, in three ways: primary extraction, or mining directly from the earth; recovery from secondary...
21. Apr. 2024 · Rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] through lutetium [Lu]).
The Journal of Rare Earths reports studies on the 17 rare earth elements. It is a unique English-language learned journal that publishes works on various aspects of basic theory and applied science in the field of rare earths (RE).
Vor 9 Stunden · ConspectusRare earth interface structure materials (RE-ISM) play a crucial role in the field of inorganic synthesis and provide an effective means of achieving the refined utilization of rare earth elements. By capitalizing on the unique properties of rare earth, these materials are designed for functional applications at interfaces. Given the escalating energy and environmental concerns ...
