The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...
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 current sources and challenges from the U.S. Geological Survey and other sources.
26 wrz 2024 · Learn about the 16 rare-earth elements, their discovery, history, and applications in modern technology. Find out why they are not so rare and where they are produced and refined.
Rare earth metals are key ingredients for making the very hard alloys used in armored vehicles and projectiles that shatter upon impact. Substitutes can be used for rare earth elements in some defense applications; however, those substitutes are usually not as effective and that diminishes military superiority.
