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 ...
[2] [3] Rare earth minerals are rare because rare earth elements have unique geochemical properties that prevent them from easily forming minerals, [4] and are therefore not normally found in deposits large or concentrated enough for mining. [4] This is the reason they are called "rare" earths.
Ferrofluid on glass, with a rare-earth magnet underneath. A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements.Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.
Rare earths are a group of 17 metals used to make magnets that turn power into motion for electric vehicles, cell phones, missile systems and other electronics. There are no known substitutes.
Last week, Ukraine agreed to a rare earth minerals deal with the US in a bid to secure support to end the war after the Trump administration dropped some of its toughest demands. But a tense ...
MP Materials CEO James Litinksy joins Yahoo Finance Live to discuss the rare-earth materials company's deal with General Motors (GM) to manufacture magnets needed for EV engines and the supply ...
Despite being among the so-called "rare earth metals", lanthanum is thus not rare at all, but it is historically so-named because it is rarer than "common earths" such as lime and magnesia, and at the time it was recognized only a few deposits were known.
Rare Earth was succeeded in 2003 by the follow-on book The Life and Death of Planet Earth: How the New Science of Astrobiology Charts the Ultimate Fate of our World, also by Ward and Brownlee, which talks about the Earth's long-term future and eventual demise under a warming and expanding Sun, showing readers the concept that planets like Earth ...
