I recall reading that Niobum does not cause allergic reations in people so that is why it is used in body piercing jewelry.
Is it pronounced with a long i or a short i -- "knee"-obium or "nigh"-obium? 171.65.102.235 22:47, 1 February 2006 (UTC)
The section on body piercing says it's used for jewelry because it is biologically inert, while below it says that dust or compounds are severe health hazards. Which is correct?
Both. The metal used for jewelry is neither a compound nor dust.-- Syd Henderson 02:43, 9 September 2006 (UTC)

This sentence was taken from the Chemical section:
“ | In the lithium niobate, the niobate ion NbO3- is not isolated but part of a perovskite-like structure, while the lantane niobate contains isolated NbO42- ions. | ” |
If you take a look at the wiki markup, you'll notice that it makes no sense. I replaced it with what I believe is the correct statement:
“ | In the lithium niobate, the niobate ion NbO3- is not isolated but part of a perovskite-like structure, while the lantane niobate contains isolated NbO42- ions. | ” |
But I may have been mistaken. Could someone with access to the Holleman book verify this? -- Cryptic C62 · Talk 17:38, 3 September 2008 (UTC)
The section Numismatics shows and describes only 2 coins of Austria in the last Euro jears, but in fact Austria produced these coins in a series of one of each jear, each jear in a different color. These series starts in 2003 and is going up to 2008 at least, this means a minimum of 8 different coins with 8 different colors a produced by the Austrian Mint. Take a look at Austrian coins. This should be statet a bit more clear. Also Lithuania has released at least one coin with violett niobium pill in 200x (?) (also produced by the austrian mint).

I wanted to nominate Niobium for a Good Article, because after hard work I feel that it has the potential to be one.-- Stone ( talk) 08:00, 19 September 2008 (UTC)
Unfortunatly, this article has not yet reached GA status. The article has some issues that need to be addressed, and I feel these could not be resolved within the seven day "on hold" period. Here is a list of improvements which need to be made in order for the article to meet the Good article criteria: -
I feel I should add that the history section of this article is very good and even though this contains chemistry it is explained well. It is in this manner that some of the other areas of the article which suffer from inclusion of technical jargon, such as the production and properties section, should be written.
If you feel this review is in error, you can ask for it to be reassesed. Otherwise, once these alternations have been made, the article can be re-nominated for good article status. Please feel free to contact me here or on my talk page if you have any problems, and good luck! Million_Moments ( talk) 18:10, 27 September 2008 (UTC)

I need a good sentence to the facts:
I added the following to the lead, meaning it as a suggestion only, since an FAC comment said the discoverers should be mentioned in the lead. However, I reverted it as SandyGeorgia complained. I will add it here, in case, there are parts you may want to use or reword:
Niobium /naɪˈoʊbiəm/ ( Greek mythology: Niobe, daughter of Tantalus), or columbium /kəˈlʌmbiəm/, is a chemical element that has the symbol Nb and atomic number 41. A rare, soft, gray, ductile transition metal, niobium is found in the minerals pyrochlore (the main source for niobium) and columbite. Niobium is similar to tantalum, and the two are difficult to distinguish. This similarity has lead to confusion over the years during process of its recognition and naming. Niobium was first discovered in columbite in 1801, by the English chemist Charles Hatchett who initially named it columbium; that mineral has since been renamed niobite. In 1846, the German chemist Heinrich Rose distinguished that niobium and tantalum were separate elements. The difference between the two was unequivocally demonstrated in 1864. However,it was not until the early 20th century that niobium was first used commercially. Now niobium is used almost exclusively to give strength to high-grade structural steels.

I noticed "aluminum" in the article, so per Wikipedia:WikiProject Chemicals/Style guidelines#Element_names I changed it to "aluminium". Given this, I checked and also found that both "color" and "colour" existed in the article; I changed all instances of "color" to "colour" given that both existed in the article and Commonwealth English is more conducive to the "aluminium" used because of the aforementioned guideline. Does anyone have a problem with these changes? {{ Nihiltres| talk| log}} 20:41, 13 November 2008 (UTC)

I got a warning that I was inserting new links and I shouldn't spam and blah balh.
Fine, but I didn't insert links... so what's up? Did I accidently remove some refrences or something? I tried to clean up a run on sentence that while probably gramatically correct was qutie difficult to read.
Didn't change meaning at all just tried to make things readable and fixed some grammer.
Did I mess up references in the process of editing and tweaking and schtuff and that prompted the warning? I didn't try to..

The South Pole telescope does not use Niobium-Nitride Bolometers. We use Aluminum-Titanium Bolometers mounted on a Silicon-Nitride mesh. The SQUID's which we use to read out the bolometers are indeed made of Niobium, as are the the mounting pads for the SQUID's (which provide the magnetic sheilding). There are many Niobium-Titanium wires as well.
I made some changes to the Nb, Ta and coltan pages back in 2006 and am only now checking them again. As the page is a far cry from the what it was five years ago and looks very professional, I would like to propose material here for discussion first before wading in with changes.
History - I consulted an 1802 paper by Hatchett to find out more about the element's history and found some interesting snippets, e.g. the name of the area where the mineral he studied is supposed to have come from: "AN ANALYSIS - OF A - MINERAL SUBSTANCE FROM NORTH AMERICA, - CONTAINING - A METAL HITHERTO UNKNOWN. - BY CHARLES HATCHETT, ESQ. -- FROM THE - PHILOSOPHICAL TRANSACTIONS. -- LONDON: - PRINTED BY W. BULMER AND CO. CLEVELAND-ROW, - ST. JAMES'S. - 1802.
"Read before the ROYAL SOCIETY, November 26, 1801.
"In the course of the last summer, when I was examining and arranging some minerals in the British Museum, I observed a small specimen of a dark-coloured heavy substance, which attracted my attention, on account of some resemblance which it had with the Siberian chromate of iron, on which at that time I was making experiments.
"Upon referring to Sir HANS SLOANE's catalogue, I found that this specimen was only described as "a very heavy black stone, " with golden streaks," which proved to be yellow mica; and it appeared, that it had been sent, with various specimens of iron ore, to Sir HANS SLOANE, by Mr. WINTHROP, of Massachusets. The name of the mine, or place where it was found, is also noted in the catalogue; the writing however is scarcely legible: it appears to be an Indian name, (Nautneauge;) but I am informed by several American gentlemen, that many of the Indian names (by which certain small districts, hills, &c. were forty or fifty years ago distinguished,) are now totally forgotten, and European names have been adopted in the room of them."
I would like to add some highlights of the above text into the history description, suitably referenced.
Steel production - alloys - I find the general description a bit weak on the following counts:
a) the greatest use of niobium is in structural and automotive micro-alloys containing 0.03% Nb
b) gas pipelines use a higher grade micro-alloy but are secondary in volume
c) the further sub-divisions of niobium alloys
Occurrence - Brazil and Canada are indeed the major producers, however I would like to list some of the minor producers. I would also like to distinguish the deposits which are being actively developed, versus other deposits which are still in the exploration stage, plus add some countries with significant deposits e.g. Gabon.
Electroceramics - Hypoallergenic - simply point out (consistent with other text in the article) that these characteristics are shared with tantalum, in order not to give the false impression that they are unique to niobium.
Obviously all text would be referenced to books and/or conference papers. Thanks for your feedback.

John Winthrop F.R.S. is Winthrop the Younger's (the governor's) grandson, and is, in turn, the great-grandson of the founder of the colony. As far as I know he does not have his own wikipedia article. Sources point to him being the discoverer of columbite. John Winthrop (1714-1779) is the great-great grandson of the founder of the colony. Confusing, but there is no inconsistency as far as I can tell. Breadblade ( talk) 23:22, 24 April 2013 (UTC)

Hi, I'm new here. I just noticed the atomic number in the heading has four digits. It says it is 41 in the next section, a two digit number more appropriate to the periodic table. Maybe my smartphone is partly at fault somehow. It is a Moto G android. — Preceding unsigned comment added by Jeffreagan ( talk • contribs) 05:06, 12 March 2017 (UTC)
A mystery remains. A four digit Atomic Number appeared below the title in smaller font. I think the first two numerals were sixes and the last was a nine, but I can't be sure. Title may have rendered with more white space. Today all systems render correctly; Win 7, Ubuntu, and Android. It must have been a glitch on my end. No artifacts remain.

seems a little more complicated than that, since the 9th edition of the Britannica in the 1880s used Niobium but the 11th edition in the 1910s switched to Columbium. Did some Brits also prefer to use their countryman's name for the element? or is this just an accident of the edition of the Britannica copied at Wikisource? — LlywelynII 05:41, 16 January 2019 (UTC)

In the paragraph Niobium-based alloys it is specified that the alloy consists of 89% Niobium, 10% Hafnium and 1% Titanium.
This seems to be misleading, is there a convention that this is called niobium-titanium instead of niobium-hafnium-titanium?

"In the course of the last summer, when I was examining and arranging some minerals in the British Museum, I observed a small specimen of a dark-coloured heavy substance, which attracted my attention, on account of some resemblance which it had with the Siberian chromate of iron, on which at that time I was making experiments.
"Upon referring to Sir HANS SLOANE's catalogue, I found that this specimen was only described as "a very heavy black stone, " with golden streaks," which proved to be yellow mica; and it appeared, that it had been sent, with various specimens of iron ore, to Sir HANS SLOANE, by Mr. WINTHROP, of Massachusets. The name of the mine, or place where it was found, is also noted in the catalogue; the writing however is scarcely legible: it appears to be an Indian name, (Nautneauge;) but I am informed by several American gentlemen, that many of the Indian names (by which certain small districts, hills, &c. were forty or fifty years ago distinguished,) are now totally forgotten, and European names have been adopted in the room of them."
I would like to add some highlights of the above text into the history description, suitably referenced.
Steel production - alloys - I find the general description a bit weak on the following counts:
a) the greatest use of niobium is in structural and automotive micro-alloys containing 0.03% Nb
b) gas pipelines use a higher grade micro-alloy but are secondary in volume
c) the further sub-divisions of niobium alloys
Occurrence - Brazil and Canada are indeed the major producers, however I would like to list some of the minor producers. I would also like to distinguish the deposits which are being actively developed, versus other deposits which are still in the exploration stage, plus add some countries with significant deposits e.g. Gabon.
Electroceramics - Hypoallergenic - simply point out (consistent with other text in the article) that these characteristics are shared with tantalum, in order not to give the false impression that they are unique to niobium.
Obviously all text would be referenced to books and/or conference papers. Thanks for your feedback.

Hurry Ma... grab the younguns. We gotta' be grabbing a claim and get a grubstake over yonder 'cross the holler in Elk City, Nebraska. Them city slickers done found some of that niobium stuff and we gotta' be grabbin' us some.
Sure ain't no jobs to be had and the younguns and I are mighty tired of nuthin' but road-kill possun stew fer' dinner.
And what with all the money being sent up, up forever up to those way up thar' atop the socio-economic hierarchy this may be to only way we can ever eat some of that high-falutin' store-bought food.
Excuse me while I butt in. IF there IS a real deposit there sumpthin' tells me it may have been deposited by a meteorite impact.

I don't know how can we trust wikipedia anymore?? — Preceding unsigned comment added by 188.230.174.229 ( talk) 20:34, 25 September 2011 (UTC)
Hello! This is a note to let the editors of this article know that File:Niobium crystals and 1cm3 cube.jpg will be appearing as picture of the day on February 1, 2012. You can view and edit the POTD blurb at Template:POTD/2012-02-01. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks! — howcheng { chat} 23:07, 31 January 2012 (UTC)

It was 1734 not 1750s. (sorry) The journal article from 2003 says the Hans Sloane 1660 - 1753 got it before Winthorp became FRS in 1734 so ....-- Stone ( talk) 20:41, 27 November 2008 (UTC)
John Winthrop F.R.S. is Winthrop the Younger's (the governor's) grandson, and is, in turn, the great-grandson of the founder of the colony. As far as I know he does not have his own wikipedia article. Sources point to him being the discoverer of columbite. John Winthrop (1714-1779) is the great-great grandson of the founder of the colony. Confusing, but there is no inconsistency as far as I can tell. Breadblade ( talk) 23:22, 24 April 2013 (UTC)
Niobium is added to glass in order to attain a higher refractive index, a property of use to the optical industry in making thinner corrective glasses.
Could anyone provide source to this statement? A Google search only gives copies/mirrors of this article. Yinweichen ( talk) 17:10, 11 March 2014 (UTC)
Pandaite is a hydrated bariun-strontium pyrochlore found in biotite-rich contact-metamorphic rocks at the Panda Hill niobium deposit in Tanzania [8] Since 2012, Cradle Resources has started development on the Panda Hill niobium deposit in the Mbeya region in southern Tanzania. This is planned as an open pit mining ooperation. [9] and [10]
Kenya's deposits found in Kwale are ranked amongst the top six in the world. [11] Recently, NioCorp has considered opening a mine in Elk Creek, Nebraska to begin domestic production in the United States. [12]
Hi, I'm new here. I just noticed the atomic number in the heading has four digits. It says it is 41 in the next section, a two digit number more appropriate to the periodic table. Maybe my smartphone is partly at fault somehow. It is a Moto G android. — Preceding unsigned comment added by Jeffreagan ( talk • contribs) 05:06, 12 March 2017 (UTC)
A mystery remains. A four digit Atomic Number appeared below the title in smaller font. I think the first two numerals were sixes and the last was a nine, but I can't be sure. Title may have rendered with more white space. Today all systems render correctly; Win 7, Ubuntu, and Android. It must have been a glitch on my end. No artifacts remain.

seems a little more complicated than that, since the 9th edition of the Britannica in the 1880s used Niobium but the 11th edition in the 1910s switched to Columbium. Did some Brits also prefer to use their countryman's name for the element? or is this just an accident of the edition of the Britannica copied at Wikisource? — LlywelynII 05:41, 16 January 2019 (UTC)

The description of the image right now:
Apollo 15 CSM in lunar orbit with the dark rocket nozzle made from niobium-titanium alloy
In the paragraph Niobium-based alloys it is specified that the alloy consists of 89% Niobium, 10% Hafnium and 1% Titanium.
This seems to be misleading, is there a convention that this is called niobium-titanium instead of niobium-hafnium-titanium?
Aditionally the artile for Niobium–titanium only mentions its usage as a superconductor. Flo422 ( talk) 02:44, 7 November 2020 (UTC)
