Rare-earth Element
The rare-earth elements (REE), also called the rare-earth metals or (in context) rare-earth oxides or sometimes the lanthanides (yttrium and scandium are usually included as rare earths), are a set of 17 nearly-indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare earths have diverse applications in electrical and electronic components, lasers, glass, magnetic materials, and industrial processes. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties, but have different electronic and magnetic properties. These metals tarnish slowly in air at room temperature and react slowly with cold water to form hydroxides, liberating hydrogen. They react with steam to form oxides, and at elevated temperature (400°C) ignite spontaneously. These elements and their compounds have no biological function other than in several specialized enzymes, s ...

Rare-earth Mineral
A rare-earth mineral contains one or more rare-earth elements as major metal constituents. Rare-earth minerals are usually found in association with alkaline to peralkaline igneous complexes, in pegmatites associated with alkaline magmas and in or associated with carbonatite intrusives. Perovskite mineral phases are common hosts to rare-earth elements within the alkaline complexes. Mantle-derived carbonate melts are also carriers of the rare earths. Hydrothermal deposits associated with alkaline magmatism contain a variety of rare-earth minerals. The following includes the relatively common hydrothermal rare-earth minerals and minerals that often contain significant rare-earth substitution: *Aeschynite-( Y or Ce) *allanite *apatite *bastnäsite *britholite * brockite *cerite * Dollaseite-(Ce) *fluocerite *fluorite * gadolinite *monazite *parisite-( Ce or La) *stillwellite *synchysite *titanite *wakefieldite *xenotime *zircon Zircon () is a mineral belonging to the grou ...

Rare-earth Magnet
Rare-earth magnets are strong permanent magnets 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. The magnetic field typically produced by rare-earth magnets can exceed 1.2 teslas, whereas ferrite or ceramic magnets typically exhibit fields of 0.5 to 1 tesla. There are two types: neodymium magnets and samarium–cobalt magnets. Rare-earth magnets are extremely brittle and also vulnerable to corrosion, so they are usually plated or coated to protect them from breaking, chipping, or crumbling into powder. The development of rare-earth magnets began around 1966, when K. J. Strnat and G. Hoffer of the US Air Force Materials Laboratory discovered that an alloy of yttrium and cobalt, YCo5, had by far the largest magnetic anisotropy constant of any material then known. The term "rare earth ...

Rare Earth Hypothesis
In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity such as sexually reproducing, multicellular organisms on Earth (and, subsequently, human intelligence) required an improbable combination of astrophysical and geological events and circumstances. According to the hypothesis, complex extraterrestrial life is an improbable phenomenon and likely to be rare throughout the universe as a whole. The term "Rare Earth" originates from '' Rare Earth: Why Complex Life Is Uncommon in the Universe'' (2000), a book by Peter Ward, a geologist and paleontologist, and Donald E. Brownlee, an astronomer and astrobiologist, both faculty members at the University of Washington. In the 1970s and 1980s, Carl Sagan and Frank Drake, among others, argued that Earth is a typical rocky planet in a typical planetary system, located in a non-exceptional region of a common barred spiral galaxy. From the principl ...

Rare Earth (band)
Rare Earth was an American rock band from Detroit, Michigan. According to ''Louder'', "Rare Earth’s music straddles genres and defies categorisation, slipping seamlessly between the two seemingly disparate worlds of classic rock and R&B." The band was signed to Motown's Rare Earth record label. Although not the first white band signed to Motown, Rare Earth was the first big hit-making act signed by Motown that consisted only of white members. (None of the previously signed all-white acts, the Rustix, the Dalton Boys or the Underdogs, had any hits.) History 1960s The group formed in 1960 as the Sunliners and changed its name to Rare Earth in 1968. The band felt the name "Rare Earth" was more in keeping with the names other bands were adopting, such as Iron Butterfly, more "with it." After recording an unsuccessful debut album, ''Dream/Answers'', on the Verve label in 1968, the group was signed to Motown in 1969. The band was one of the first acts signed to a new Motown impri ...
