Talk:Nickel

Article changed over to new Wikipedia:WikiProject Elements format by Dwmyers 19:59 Feb 24, 2003 (UTC). Elementbox converted 15:08, 2 July 2005 by Femto (previous revision was that of 05:29, 14 June 2005).

Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Nickel. Additional text was taken directly from USGS Nickel Statistics and Information, USGS Periodic Table - Nickel, from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). 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.

Errors in production data?

They claim that Canada produces 30 percent of world nickel, and the implied claim that it is the biggest producer, seem to contradict other sources in the Internet. Russian nickel production is almost twice as high as Canada's, and most sources say that Russia is the biggest producer.

Talk

The amount of nickel which is allowed in products which come into contact with human skin is regulated by the European Union. In 2002 a report in the journal Nature researchers found amounts of nickel being emitted by 1 and 2 euro coins far in excess of those standards. This is believed to be due to a galvanic reaction.

wouldn't the quantity of nickel exposure from dental braces be far above any contact from handling coins? Crusadeonilliteracy

I know that I can not wear many earings because nickel in the posts make my earlobes swell up.

This is an allergic reaction which often happens from contact with some metals. I believe a thing niobium plating resolved that problem.

Rainey Nickel

I think the following use of Nickel is called Rainey Nickel, but I do not know how to spell it.

Finely divided nickel is a catalyst for hydrogenating vegetable oils.

ok, it's awesome info n' all but i need to know what things have nickel in them!

Adding sections

I'm new to Wikipedia, but if someone could tell me how to start a new section on the uses of Nickel, it would be a useful section.

To add a section simply go to the 'edit this page' tab at the top of the page. Reading the guidelines would also be a good idea.

Allergic Reactions

Can we change to:

Nickel is the most ubiquitous contact allergen among children and adolescents. If its in contact with the skin like ear rings, blue jeans buttons and belts sensitised individuals may show an allergy to nickel affecting their skin. (byer and Morrell) The amount of nickel which is allowed in products which come into contact with human skin is regulated by the European Union.

Nickel is the most ubiquitous contact allergen among children and adolescents. First sentence from abstract:

• Byer TT, Morrell DS (2004). "Periumbilical allergic contact dermatitis: Blue jeans or belt buckles?". Pediatric Dermatology. 21: 223–226.DOI]

Some guitar strings are made of nickel and may affect people who are allergic to nickel. You can check the little paragraph I added to the Guitar talk section: http://en.wikipedia.org/wiki/Talk:Guitar (Health Issues)... --Lethaljellybean 23:39, 1 October 2006 (UTC)

Russia Nickel Export

MMC Norilsk Nickel is a privately held company that is deeply involved in the export of nickel from Russia. The sentence about "Russia using its 40% of the world's supply of nickel for its own domestic use" doesn't really make sense. The ore is smelted in Norilsk and the nickel is sold on the world market for the highest price and I am sure that Russia is not going to ever suffer a shortage of nickel, like Venezuela will never suffer a shortage of crude oil, no matter how much is sold. --McTrixie 11:41, 28 September 2006 (UTC)

"Metallurgical Industry of Russia": For 2006: Russia's nickel exports to countries outside the CIS in January-July increased by 5.5% on the year, to 143,600 metric tons, according to the federal customs service. Total nickel exports, including CIS states, were 143,900 tons.

MMC NN produces about 250,000 metric tons per year total.--McTrixie 11:49, 28 September 2006 (UTC)

phytoremediation

Is it relevant to add here some phytoremediation-related information relevant to nickel? There's some here: Hyperaccumulators table – 2 : Nickel, with particular attention to the notes at the end of the table, and to notes relevant to Streptanthus polygaloides and Thlaspi montanum. There are more to come of the same style, I just haven't developped that side for lack of where to put the info. I have the same question about quite a few metals, notably Cadmium (note with Tagetes erecta in Hyperaccumulators table – 1, and some), copper, lead, etc, incl. radionuclides. What/where do you think this should go? Basicdesign 05:30, 29 October 2006 (UTC)

Nickel

is it nickel is a recyclable material?

Extraction section

I have a few problems with the section on extraction: First, the article says "Most lateritic ores have traditionally been processed using pyrometallurgical techniques to produce a matte for further refining." I would say that most lateritic ores have been traditionally avoided, because they are so difficult to process! And the "traditional" matte smelting route is applied to sulfide ores, i.e. floation, partial roasting, electric or reverb smelting; or skip the partial roast and flash smelt. That's enough... I'll save my other quibbles with that section for laterBSMet94 06:20, 18 January 2007 (UTC) Revising my previous statemtent, I should have said that traditionally laterits have been avoided for production of elemental nickel. Obviously, the rotary kiln/electric furnace process has been around for quite a while in the production of ferronickel, which isn't exactly pure nickel production. Just thought I'd clarify my remarks. Isn't anyone going to correct that section, or are you waiting for me to do it? heheheh BSMet94 06:26, 16 February 2007 (UTC)

Subject: at odds with "The Most Tightly Bound Nuclei"

Why do the masses (2003) for Fe-56 and Ni-62 show that m/A is lower for Fe-56, which is different from B/A?

That's a good point; neutròns suffer more from the nuclear bonds.

mn-mp = .001388

Ni-62: 61.9283451u, .99884428u/A

Ni-60: 59.9307864u, .99884644u/A

Ni-64: 63.9279660u, .99887447u/A

Fe-56: 55.9349375u, .99883817u/A

Fe-58: 57.9332756u, .99884958u/A

.99884428-.998833817=.000010463

mp = 1.00727646688u; mn = 1.00866491578u

However, that brings up a new problem, that Ni-64 seems to win out:

Ni-62: 28mp + 34mn = 62.4983482u -> 61.9283451u => .5700031u

Ni-60: => .5502320u

Ni-64: => .5877120u

Fe-56: 26mp + 30mn = 56.4491356u -> 55.9349375u => .5141981u

Fe-58: => .5331898u

Never mind! I didn't divide by A: .0091936, .0091705, .0091830, .0091821, .0091829. Then the strongest nuclei are Ni-62, Ni-64, Fe-58, Fe-56, Ni-60.

magnetic properties

someone should perhaps add to the article that Ni is a quite interesting magnetic material, as it is a highly itinerant ferromagnet, shows extraordinary large longitudinal fluctuations of the local magnetic moment and due to these properties it has proven until recently extremely difficult to estimate its thermal properties through the standard methods of ab-initio thermodynamics. See e.g. Phys. Rev. B 75, 054402 (2007), Phys. Rev. B 64, 174402 (2001), Phys. Rev. B 71, 214435 (2005) Yes, I could write up something myself, but first I'm no native speaker and second, I've got work to do.

Radius of Nickel

I believe what you have in the article is the diameter rather than the radius. Check Helen G. Hansma et Al., DNA binding to Mica correlates with cationic radius: Assay by AFM, Biophysical Journal V. 70 April 1996 1933-1939. However, in the above they give the ionic radius and I think they refer to the hydrated radius but it is more likely than the one in the article in wikipedia anyway. —The preceding unsigned comment was added by 86.145.166.61 (talk • contribs).

Reference is atomic radii of the elements (data page). The articles use a set of data with consistent definitions taken from webelements.com, for what it's worth. Femto 14:52, 28 May 2007 (UTC)

The atomic radius is listed as 135 pm, but the Los Alamos Labs (which the article cites) lists the atomic radius as 124.6 pm. 99.233.162.203 (talk) 05:53, 7 January 2008 (UTC)

Canadian Nickel

I have found the Canadian Nickel after 1958 is not magnetic. It was also when Canada stopped making the polygon shaped one also. The article states it was magnetic on some dates up to 1989, I would like to know what those dates are.
