What are Rare Earth Elements?
Rare Earth Elements (REE), also known as Rare Earth Minerals and Rare Earths, are a group of 17 elements composed of the chemical category known as lanthanides and the elements yttrium and scandium1. REE have several unique properties that make them valuable in a variety of civilian and military high-technology applications. Small amounts of REE enable the miniaturization of a number of high technology components, especially permanent magnets. On the civilian side, REE are integral to LCD screens, fiber-optic cables, rechargeable batteries, various appliances, and are increasingly becoming valuable for their use in ‘green’ technologies such as wind power generation and hybrid motor vehicles. Their military utility is enormous and includes applications ranging from aircraft engines and precision-guided munitions to communication and tracking satellites2.
