rare earth element

Also known as REE, REM, rare earth elements, rare-earth elements, rare earth metal, rare earth metals, lanthanides, lanthanide series

any of the fifteen lanthanides plus scandium and yttrium

AI overview

Rare earth elements are a group of 17 chemical elements (the fifteen lanthanides plus scandium and yttrium) that are used in many modern technologies and products. They matter because they're essential for manufacturing everything from smartphones and wind turbines to military equipment, making them strategically important for economies and national security.

Encyclopedic overview

Rare-earth elements in the periodic table

The rare-earth elements (REE), also called rare-earth metals, or rare earths, are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. The 15 lanthanides (or lanthanoids), along with scandium, and yttrium, are usually included as rare earths. Compounds containing rare-earth elements have diverse applications in electrical and electronic components, lasers, glass, magnetic materials, and industrial processes. Rare-earths are to be distinguished from critical minerals, which are materials of strategic or economic importance that are defined differently by different countries, and rare-earth minerals, which are minerals that contain one or more rare-earth elements as major metal constituents.
