Neodymium
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.

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 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. Materialscientist (talk) 00:05, 16 October 2009 (UTC)

morse code

 * 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. 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 —Preceding unsigned comment added by 24.15.124.119 (talk) 23:44, 14 April 2008 (UTC)

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. —Preceding unsigned comment added by 98.244.71.39 (talk) 01:27, 4 November 2009 (UTC)

Meh?
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.  2J Bäkkvire Maestro  Test UR Skill! What I've Done 04:58, 15 February 2010 (UTC)


 * 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]" --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). Materialscientist (talk) 12:47, 3 February 2013 (UTC)


 * This article gives the gives the bastenasite from Mountain Pass with 33.79% La; 45.59%; Pr 4.65%; Nd 15.82% (100% = REO+Y2O3).--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 my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
 * Added archive https://web.archive.org/web/20100213081554/http://www.gelighting.com/apo/resources/learn_about_light/history_of_light.htm to http://www.gelighting.com/apo/resources/learn_about_light/history_of_light.htm

Reformat
Article changed over to new 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 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)

"Tyrium" listed at Redirects for discussion
A discussion is taking place to address the redirect Tyrium. The discussion will occur at Redirects for discussion/Log/2021 April 21 until a consensus is reached, and readers of this page are welcome to contribute to the discussion. –LaundryPizza03 ( d c̄ ) 17:45, 21 April 2021 (UTC)

Images
Article probably needs more cleanup, and also deal with the images sandwiching. If the issues wasn't fixed, then some reviewer at GAN will most likely quick fail it. 2001:4455:364:A800:75C8:6EE4:66A9:382A (talk) 01:15, 8 February 2022 (UTC)

I have just fixed this issue, thanks for noting it! Bli231957 (talk) 20:47, 8 February 2022 (UTC)

Orphaned references in Neodymium
I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Neodymium's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "Greenwood1229": From Cerium: Greenwood and Earnshaw, pp. 1229–1232 From Praseodymium: Greenwood and Earnshaw, p. 1229–32 

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT ⚡ 06:33, 6 February 2022 (UTC)

Marks Brothers
Who are Marks brothers as mentioned in Neodymium so that their opinion on the name is relevant? Jariola (talk) 15:05, 31 March 2022 (UTC)
