Most REEs are not as rare as the group's name suggests. They were named "rare-earth elements" because most were identified during the 18th and 19th centuries as "earths" (originally defined as materials that could not be changed further by heat) and in comparison to other "earths," such as lime or magnesia, they were relatively rare.

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 …

In this time of increased focus on renewable energy technologies, rare earth elements (REEs) are of critical importance. For example, neodymium (Nd) is a REE used in the generator and motor magnets of wind turbines and electric vehicles. Reliance on REE imports puts the U.S. at high risk for supply disruption.

Green channel of fast publication for the major breakthrough. Selected cover figure and cover story.

What are Rare Earths? Rare earth elements are chemical elements including yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium). The rare earth elements are all metals, and have many similar ...

Notably, approximately 40% of mined rare earth production is reduced to metals and alloys, including most of neodymium (Nd), samarium (Sm), and dysprosium (Dy), for applications such as neodymium metal for Nd-Fe-B permanent magnets, samarium metal for Sm-Co permanent magnets, lanthanum (La), cerium (Ce), praseodymium (Pr), and …

Rare-earth element - Abundance, Occurrence, Reserves: As noted above, the rare earths are fairly abundant, but their availability is somewhat limited, primarily because their concentration levels in many ores are quite low (less than 5 percent by weight). An economically viable source should contain more than 5 percent rare earths, unless they …

Rare earths – which include exotic-sounding elements like dysprosium, cerium, and ytterbium – are actually more abundant than other familiar metals, but tend to become concentrated in less ...

Rare earth metals are a group of chemical elements you can find next to each other on the periodic table, including the 15 lanthanide elements, yttrium, and scandium. All the rare earths are metals with similar properties that lead them to appear in the same geologic deposits. Despite their name, even the scarcest rare earth elements …

Terbium (Tb), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Terbium is a moderately hard, silvery white metal that is stable in air when in pure form. The metal is relatively stable in air even at high temperatures, because of formation of a tight, dark oxide. Scandium (Sc), chemical element, a rare-earth ...

Rare-earth element - Minerals, Ores, Uses: The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as "light" or "heavy"; in the former group most of the elements present are the light-atomic-weight elements (i.e., lanthanum, cerium, …

Even the rarest rare earth, thulium, with atomic number 69, is 125 times more common than gold. And the least-rare rare earth, cerium, with atomic number 58, is 15,000 times more abundant than gold.

The rare earth elements (REEs), also called rare earth metals or just rare earths (REs), have been the most prominent and discussed raw materials since about 2009. In that year, China announced a reduction in REE export quotas of nearly 50% to 30,000 tons (t) 1 rare earth oxides (REOs) (the usual measure for traded RE materials) ( Zepf, …

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...
