[edit] Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Platinum. Additional text was taken directly from USGS Platinum Statistics and Information, 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 were obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but were reformatted and converted into SI units.

I ld just like to ask if you could state ALL the different isotopes in this section as i would find it interesting to know them all- Posted by DarrenLepper (darrenlepper2004@yahoo.co.nz) 08-06-04

[edit] Formatting

I don't know Wiki formatting, but does anyone else see this page as very screwed up? The notable characteristics header starts about a page before the paragraph. 134.226.1.234 15:52, 13 February 2007 (UTC)

Yep, its a mess. Not too up on formatting myself at this juncture or I'd have a go at it. Drrocket 17:45, 13 February 2007 (UTC)

Agreed. I moved the "alchemy" symbol because it was overwriting the adjacent text. Tried it in various places, but it always makes a mess of any nearby text. The other images are not where they're supposed to be, but the text is readable, so I left them alone Hoserjoe 06:50, 23 July 2007 (UTC)

[edit] Density

There are various references that state the density of platinum to be 21.45, eg

[1]

I also checked a paper source, the CRC Handbook of Chemistry and Physics, 60th Ed, pages B-17 and B-106, which also gives 21.45 at 20 deg C.

See also Talk:Density

I am not sure of the protocol in such areas where the appear to be various reputable sources that give differnt data..but I tend to side with the paper book!

--GPoss 06:53, Aug 22, 2004 (UTC)

I know about WP:OR but I had some platinum machined into 1cc blocks - and according to my kitchen scales, they weight 21.45kg for 1 litre - so I'm happy with 21.45g/cm³. Stephen B Streater 08:21, 27 May 2006 (UTC)

[edit] Very interesting

I found this on Anglo Platinum website. Could never have guessed some of these stuff have platinum "Platinum's use in the manufacture of silicones has grown over the last few years and now accounts for the largest proportion of chemical demand for platinum. It is completely consumed in the process, and demand increases directly with output. Silicones are used in the manufacture of pressure-sensitive adhesives, release liners, and water-repellent coatings. Pressure-sensitive adhesives are used in Post-it® notes, while release liners are used in re-sealable plastic bags. Water-repellent coatings have a vast array of applications, among them furniture polish and cleaning products. Platinum demand was unchanged, given no significant increase in output of these chemicals."

[edit] Amount Mined

If anyone knows approximately how many tons or ounces of Platinum is mined each year, that would be an interesting fact to add. KellyCoinGuy 06:59, 31 October 2005 (UTC)

This financial BB (which is free to register on) reckons on about 6m Oz/year in 2002. But it's not really a reliable source, despite the nice pie charts. I'll see what I can find. Stephen B Streater 08:27, 27 May 2006 (UTC)

Other links to cites on production: 1997 report 2004 and more respectable source BBC report. So I think around 6m Troy oz/year is a good estimate. I'll add something to the article. Stephen B Streater 08:35, 27 May 2006 (UTC)

The article says:

[edit] World production

World supply of platinum is around 7 million troy ounces (199,000 kg) per year. ^[1][2] Platinum's cost fluctuates around USD $1100 per ounce ($35/g). [2]

--Kalmia 23:25, 27 January 2007 (UTC)

Both the USGS ( United States Geological Survey )[3] and Johnson Matthey [4] report on historical platinum supply. Since supply has been increasing relatively rapidly (from 5 million oz in 1997 to 7 million in 2006), it seems more appropriate to indicate the year next to the data. If price is to be included, it seems critical that a date be included because Platinum prices have been so volatile (in 1999 it was less than $400/oz and on Aug.13, 2007 it was more than $1270/oz) [5]. I agree with posting below about costs that a historical range of prices and links need to be included. -- Elisa 4:20pm, August 13, 2007

[edit] cost

is the industrial pricing for platinum relivent for encyclopedia content? the article states it costs 1.5times as much as gold, so i guess it is. research, anyone? mastodon 02:48, 5 January 2006 (UTC)

I second that. I just came to this article looking for the price of platinum and couldn't find anything. This would easily qualify as encyclopedic content so long as it is qualified with a date, i.e., "As of 2006-03-02 the price of platinum on the commodities market was around $700 an ounce." --Cyde Weys 15:13, 2 March 2006 (UTC)

1 ounce of Platinum is $1,293.00 USD. Keep in mind 1 ounce of Gold is $652.65 USD. These are the current standings for May 26, 2006.

-G

As the price is quite volatile, I suggest a more encyclopaedic reference would be to the range of prices over a certain period eg 1995 low and high, Q1 2006 High and Low. People don't come here for news, but a link to eg kitco.com gives the current price. And prices over the last complete quarter would be easier to update and maintain in future when we're all gone. Stephen B Streater 08:19, 27 May 2006 (UTC)

Since this is the internet, it's most useful to link to daily price charts. I'll come back later and have a go at it, but if I don't, feel free to do it yourself. Try http://www.platinum.matthey.com/prices/price_charts.html

[edit] Information

Is there an article or website I can go to on how to separate Platinum from iron. 24.216.237.219 01:42, 11 June 2006 (UTC)SA June 10, 2006

[edit] PLatinum in medical implant devices

references to platinum as a catalyst in silicone medical devices added. Concerns over potential toxicity recieved some press recently and have been addressed by the FDA. Link attached Droliver

No link attached. In any event, this is an article about platinum, not breast implants. There is an article about breast implants on Wikipedia. Gfwesq 01:53, 28 June 2006 (UTC)

FDA link is attached for a review related specifically to platinum. Platinum is a catalyst used in the curing of silicone in dozens of different medical implant devices (orthopedic implants, breast implants, testicular & penile prosthesis, spine hardware, artificial heart valves, etc....)Droliver 17:52, 28 June 2006 (UTC)

Looks like a legitimate issue on the biological effects of platinum to me. Femto 18:31, 28 June 2006 (UTC)

Therefore, I left your last edit, Femto, where there is a link to breast implants. The FDA has been asked by other scientists for more research to refute or confirm the 2006 study. This is not a discussion on breast implants. At the most, it should be mentioned as you did, with a link. The other medical devices do not have a paragraph on it. Oliver simply wants to push his interest in breast implants all over wikipedia, in every article he can. IT is not appropriate.MollyBloom 17:15, 29 June 2006 (UTC)

platinum is the catalyst in dozens of different medical devices and as such this is a relevent aside. The study in Analytic Chemistry re potential platinum toxicity would apply to many different devices. This claim has been reviewed and dismissed by the FDA, Health Canada, and the British health ministry. Even analytic chemistry is now publicly saying they do not have faith in the methods and results of that research.Droliver 15:29, 8 August 2006 (UTC)

Pure Platinum, when cast and un-worked is quite soft, much like Gold, and makes only a dull 'thunk' when struck. If rolled into a plate, it work-hardens to some extent and will make a higher pitched sound when struck but not a 'ring' at all, the tone being rather flat. The only time I ever got Platinum to 'ring' when struck was as a cast 95% Pt 5% Pd bar. This alloy produced a pure bell-like tone when struck. Drrocket 17:42, 17 November 2006 (UTC)

That 5ppb is the crustal average; the 0.5ppm (or 500ppb) in the Sudbury ore indicates a hundred-fold enrichment over the average, that's why it's ore. Vsmith 13:32, 12 November 2006 (UTC)

[edit] Color

"When pure the metal appears greyish-white and firm."

Not at all certain what is meant by "firm" in this case. Both the pure sponge, obtained by thermal decomposition of Ammonium Hexachloroplatinate, and the pure powdered metal are light-grey in color but the massive form obtained from melting pure sponge or powder is silver in color without the white tones one finds with actual Silver. If anything, there is the slightest hint of yellow along the lines of the hints of blue seen in the massive form of Rhodium. Drrocket 18:42, 17 November 2006 (UTC)

[edit] RIAA Album notation

Should there be something here that indicates that (like with the credit card) the platinum is the highest official calibre of record sales (other than the unofficial diamond, colloquially known only, meaning 10x platinum).

I don't know the direct link, but I think it'd be appropriate to promote the status of platinum in the public eye.

anybody agree?

--lincalinca 22:24, 21 November 2006 (UTC)

There's already something in the "Rarity and color" section, which includes a (badly piped) link to Music recording sales certification. Femto 12:58, 22 November 2006 (UTC)

There's no 'see also' at the top of the page - Platinum (disambiguation) has this information. I've put a dab at the top, as with silver and gold. Proto::type 14:15, 27 November 2006 (UTC)

[edit] Mohs hardness

The mohs value of 3.5 contradicts the "4 - 4.5" given at Mohs_scale_of_mineral_hardness. I've looked at several pages on the internet and several give 3.5 while several others give 4.3. I've had great trouble figuring out which one is correct.--Father Goose 05:39, 27 November 2006 (UTC)

[edit] "Lumbare"

Lumbare [Latin] refers to the pelvic girdle in general whereas Lumbar is a location modifier for vertebrae.

vis: Populum istum pessimum qui nolunt audire verba mea et ambulant in pravitate cordis sui abieruntque post deos alienos ut servirent eis et adorarent eos et erunt sicut lumbare istud quod nullo usui aptum est. Wherein lumbare refers to the pelvic girdle of the human body.

[edit] Giant Blank

Hey, someone going to fix that? Colonel Marksman 00:51, 8 March 2007 (UTC)

[edit] what are some common compounds that contains patinum?

jfghj —The preceding unsigned comment was added by 67.58.155.42 (talk) 01:52, 11 March 2007 (UTC).

[edit] Platinum Supplements?

In Japan they're making anti-aging supplements that contain Platinum (or say they do). The slogan on the commercials is "Platinum doesn't rust; It doesn't rust so it stays beautiful". Has anybody heard about this? Does it seem effective, ineffective, or what? Is platinum safe to injest?

[edit] The article image might be wrong.

I've noticed the image of Platinum is also the same image used for the article on Tantalum. Could someone please explain this?, as they the two metals can't possibly be the same. :-) Nateland 23:46, 13 April 2007 (UTC)

Image:Pt,78.jpg and Image:Ta,73.jpg? Look different to me. Femto 14:38, 14 April 2007 (UTC)

[edit] photos

The lead photo for most metals and elements articles feature a distinctly dull and usually uninformative representation of the appearance of the metal or element under discussion. Please provide a photo other than that of a [quite often] frosty, milky or otherwise hazy-looking substance inside a glass vial. For example, if a metal is described as being able to take on a high polish, then that metal ought to have a photo that doesn't look like a toddler's leftover morning cereal. Face it, many DO look this way, too! 71.59.70.21 01:33, 30 May 2007 (UTC)PLK

Is platinum known as white gold?

[edit] Rarity and color

This section is dreadful; it addresses neither the rarity nor the color of the element, but, rather, its use in marketing. The marketing discussion is, at best, vague (i.e. above gold and under diamond in the awards for an unknown institution) and does not cite sources. The mention of the crown of Queen Elizabeth is unnecessary trivia that, if anywhere, belongs in the article on the crown itself. I would propose to remove this section. Thoughts?

[edit] Swimming Pool

It says that all the platinum mined in the world comes to two hundred thousand kilos a year - but also that the total amount of platinum in the world would only fill four inches of a swimming pool. Does this strike anyone else as odd? 80.229.160.127 (talk) 21:31, 20 November 2007 (UTC)

Go to: http://www.simetric.co.uk/si_metals.htm

The site says that one cubic meter of platinum weighs 21,400 kilograms. Thus "over 200,000 kilograms" would be about ten cubic meters of the metal. I'm not too sure what the square footage of an average swimming pool might be, but slicing these cubic meter cubes into 10 centimeter slices (approximately 4 inches, for the sake of argument) would produce 100 slices, or 100 square meters, that's a 10 square meter pool. Not tiny, but not huge. —Preceding unsigned comment added by 75.143.208.234 (talk) 19:09, 27 February 2008 (UTC)

So that would mean that the entire world supply of platinum would be mined out in one year... 80.229.160.127 (talk) 19:11, 27 February 2008 (UTC)

No, that means one years production gives 10 cm in a 100 m^2 pool. But an olympic size swimming pool is 1250 m^2, so that's 12 years of production. If we're talking reserves (as it says in the article), the kind that's not been mined yet, 12 years of production in proven reserves is pretty standard for a mine. But if we're talking about the total amount ever mined, 12 years of the current production seems a bit low. Either way, swimming pools is a strange metric, and the statement should be backed by a real number.81.235.136.245 (talk) 02:37, 10 March 2008 (UTC)

The source for this statement is "Retail Jewelers of Ireland". Given the amount of inaccurate information I have been told by jewelers in the past, I have difficulty accepting this as an authoritative source. Given the dubiousness of the claim, we either need a better source for this statement or to remove it altogether. Egomaniac (talk) 14:37, 28 April 2008 (UTC)

--- I have found this claim, and the fact that the only sources that claim it being jewelers, to be odd. I am a chemistry student and I have a chart from quickstudy.com that says that the "Elemental Abundance mg per kg of crust" of platinum is .005, while that of gold is .004. In other words, it is estimated that gold is actually rarer than platinum. Chemists and car manufacturers use platinum, although palladium, being more abundant, is preferable when it can be used. RegiG (talk) 02:17, 5 June 2008 (UTC)

[edit] Rarity and color

The section "Rarity and color" should be renamed, as it does not give details on the rarity of the metal and says nothing about the color; it only describes the symbolic prestige associated with it. I suggest "Symbolic prestige" as the new title. Mal7798 (talk) 19:38, 10 February 2008 (UTC)

[edit] Production
