I'll bring back the misspelling information that was recently removed. The misspelling "neodynium" is not notable in Wikipedia because I've corrected all of its occurrences (except one that is in a reference title on [[IntraLASIK]]) since I started editing here. Google "neodynium" and you'll find many serious scientific papers using it. The misspelling "praseodynium" can be seen much less frequent but is still worth mentioning too, I think.

:''Didymium glass was used during World War I to send Morse Code across the battlefields. The glass filter caused only imperceptible fluctuation in the overall light intensity, but the intended receiver had a set of binoculars fitted with a spectroscope wherewith to see the neodymium absorption bands flashing on and off.'' |

Seems unlikely. Removed pending citations etc. [[Special:Contributions/24.95.50.240|24.95.50.240]] ([[User talk:24.95.50.240|talk]]) 06:47, 25 November 2007 (UTC) |

there is perhaps more nonsence in old glas section. Leo vel Ludvig die 1916 and the Czech "Moser Company" glass was awrded in Paris in 1925 thus before "its discovery" in 1927 a s the article claim . http://www.moser-glass.com/en/tradition/glass-museum <small>—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/24.15.124.119|24.15.124.119]] ([[User talk:24.15.124.119|talk]]) 23:44, 14 April 2008 (UTC)</small><!-- Template:UnsignedIP --> <!--Autosigned by SineBot--> |

The book "Moser 1857 - 1997" officially published by the Moser company, by Jan Mergl and Lenka Pankova, describe the 1927 experiments, and reference the Leo Moser papers now in the Corning Glass Museum, Corning New York. The 1925 Award had nothing whatsoever to do with rare earth glass coloration. <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/98.244.71.39|98.244.71.39]] ([[User talk:98.244.71.39|talk]]) 01:27, 4 November 2009 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot--> |

==Not Discovered in 1885== |

Apparently Neodymium was discovered in 1925 by C.F. Aver von Welsbach as detailed at http://www.chemicalelements.com/elements/nd.html [[Special:Contributions/203.206.36.108|203.206.36.108]] ([[User talk:203.206.36.108|talk]]) 12:43, 15 October 2009 (UTC) |

:That what they say. [[Carl Auer von Welsbach]] died in 1929 and was not that active (experimentally) in his last years. [[User:Materialscientist|Materialscientist]] ([[User talk:Materialscientist|talk]]) 00:05, 16 October 2009 (UTC) |

Sorry if the de-redlinking was uncalled for. But why? Redlinks are ugly. Are they there to inform people, encourage them to write about them? Answer yes/no.

:Please read [[WP:REDLINK]]. The whole issue causes me a certain amount of anger, I admit, since I have argued that redlinks be green since red causes many people to think that they are ugly or distracting and that they need to be removed for that reason alone. In that argument I alway get some idiot who says "not so!". And then I go back to WP and find people like yourself who are removing redlinks precisely for that reason.

== there is no neodym in Bastnäsite ? == |
|||
from the banästite link: "There is bastnäsite-(Ce) with a more accurate formula of (Ce, La)CO3F. There is also bastnäsite-(La) with a formula of (La, Ce)CO3F. And finally there is bastnäsite-(Y) with a formula of (Y, Ce)CO3F." |
|||
so, it should be mentioned in banästit and on neodym, that most rare earths are very similar and occur in mixed contributions. In truth, it seems even to be a Wrong citation: from the banästit link, the mineral "parisite" should be used as Banästite does Not contain neodymium as seems. "Bastnäsite is closely related to the mineral series parisite.[6] The two are both rare earth fluorocarbonates, but parisite's formula of Ca(Ce, La, Nd)2(CO3)3F2 contains calcium (and a small amount of neodymium) and a different ratio of constituent ions. Parisite could be viewed as a formula unit of calcite (CaCO3) added to two formula units of bastnäsite. In fact, the two have been shown to alter back and forth with the addition or loss of CaCO3 in natural environments.[citation needed]" --[[User:Wikistallion|Wikistallion]] ([[User talk:Wikistallion|talk]]) 12:37, 3 February 2013 (UTC) |

:I don't fully understand your point. As far as I know, any lanthanide, including Nd substitutes "La" in the bastnäsite structure, La is just more common, same for parisite. The difference between bastnäsite and parisite is mainly in the crystalline structure, not in the content of a particular lanthanide (which rather depends on geological factors).

:This article gives the {{doi:10.1111/j.1751-3928.2008.00068.x}} gives the bastenasite from Mountain Pass with 33.79% La; 45.59%; Pr 4.65%; Nd 15.82% (100% = REO+Y2O3).--[[User:Stone|Stone]] ([[User talk:Stone|talk]]) 20:41, 4 February 2013 (UTC) |

Hello fellow Wikipedians, |
|||
I have just modified one external link on [[Neodymium]]. Please take a moment to review [[special:diff/825883580|my edit]]. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit [[User:Cyberpower678/FaQs#InternetArchiveBot|this simple FaQ]] for additional information. I made the following changes: |

Reformat
Article changed over to new Wikipedia:WikiProject Elements format by schnee. Elementbox converted 11:05, 10 July 2005 by Femto (previous revision was that of 13:32, 9 July 2005).
Information Sources
Data for the table was obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.
paramagnetic
The infobox does indicate that Nd is paramagnetic, but the section on magnets doesn't. Not mentioning it, readers might assume that it is ferromagnetic, as it makes good permanent magnets. Should we say more about the magnetic properties of Nd, and its alloys? Gah4 (talk) 00:17, 30 May 2019 (UTC)
