  • Of the rare earths, only yttrium , lanthanum , and cerium are more plentiful than neodymium. (britannica.com)
  • No follow up work was ever done on some highly anomalous REE results in a number of areas within the outer ring structure of the carbonatite - the north area, despite the average combined lanthanum, cerium and neodymium oxides samples averaging 1.1% (a number of samples exceeded 4.0%), saw little advanced exploration. (mining.com)
  • Hydroxylbastnasite (also spelled hydroxyl-bastnasite) has cerium, lanthanum and neodymium in its generalized formula but officially the mineral is divided into three minerals based on the predominant rare earth element found in specimens. (galleries.com)
  • However, compounds of neodymium with transition metals such as iron can have Curie temperatures well above room temperature, and these are used to make neodymium magnets. (wikipedia.org)
  • The neodymium atom also can have a large magnetic dipole moment because it has 4 unpaired electrons in its electron structure as opposed to (on average) 3 in iron . (wikipedia.org)
  • The metal is used in the electronics industry, in the manufacture of steel , and as a component in a number of ferrous and nonferrous alloys , among them misch metal (15 percent neodymium), used for lighter flints. (britannica.com)
  • Another important use of neodymium is as a component in the alloys used to make high-strength neodymium magnets-powerful permanent magnets. (wikipedia.org)
  • In practice, the magnetic properties of neodymium magnets depend on the alloy composition, microstructure, and manufacturing technique employed. (wikipedia.org)
  • General Motors has successfully developed the melt-spinning process, which can prepare neodymium magnets. (stanfordmagnets.com)
  • It has a melting point of 1,024 ° C (1,875 ° F) and a boiling point of about 3,030 ° C (5,490 ° F). Neodymium has a density of 7.0 grams per cubic centimeter. (encyclopedia.com)
  • Neodymium is strongly paramagnetic and orders antiferromagnetically at 7.5 and 19.9 K (−265.7 and −253.3 °C, or −446.2 and −423.9 °F) with spontaneous magnetic moments developing separately on different independent sites, hexagonal and cubic, respectively. (britannica.com)
  • The major application of neodymium is in high-strength permanent magnets based on Nd 2 Fe 14 B that are used in high-performance electric motors and generators , as well as in spindle magnets for computer hard drives and wind turbines. (britannica.com)
  • The strength of neodymium magnets is due to several factors. (wikipedia.org)
  • The color of neodymium compounds-due to the Nd3+ ion-is often a reddish-purple but it changes with the type of lighting, due to the interaction of the sharp light absorption bands of neodymium with ambient light enriched with the sharp visible emission bands of mercury, trivalent europium or terbium. (wikipedia.org)
  • Neodymium magnets were discovered in 1982 by Masato Sagawa of sumitomo special metals. (stanfordmagnets.com)
  • Although neodymium is classed as a rare earth, it is a fairly common element, no rarer than cobalt, nickel, or copper, and is widely distributed in the Earth's crust. (wikipedia.org)
  • Neodymium is a chemical element with symbol Nd and atomic number 60. (wikipedia.org)
  • Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. (wikipedia.org)
  • A total of 31 radioactive isotope s of neodymium (excluding nuclear isomers) have been characterized, ranging in mass from 124 to 161 and in half-life from 0.65 second (neodymium-125) to 7.9 × 10 18 years (neodymium-150). (britannica.com)
