[edit] News sources
Anome, you changed the line I added to suggest that is just ABC reporting on this threat... but Google News shows that everyone is reporting it now. Is ABC the sole originator of the story? Pete/Pcb21 (talk) 12:06, 6 Apr 2004 (UTC)
- To answer my own question, most reports do simply refer to ABC, except the BBC, which seems to imply it has further information. Pete/Pcb21 (talk) 12:09, 6 Apr 2004 (UTC)
[edit] Page name
This is a bit late, but is osmium(VIII) oxide really a better name for this page than osmium tetroxide or osmium tetraoxide? Physchim62 (talk) 15:14, 25 July 2006 (UTC)
- I support renaming this page, I would go all the way - osmium tetroxide.--Smokefoot 22:14, 25 July 2006 (UTC)
- That was its old name, before someone moved it... Physchim62 (talk) 16:18, 26 July 2006 (UTC)
[edit] Refining
Interesting. I've looked at the citation and what is stated here is, indeed, a faithful reproduction of the citation. Not how its done though; the citation is a garbled combination of two different methods. Bulk native ore is roasted in a tube furnace while drawing air over the heated material generating OsO4 directly which is dissolved in aqueous NaOH in bubblers. The solution is saturated with KOH then methanol or ethanol added to precipitate Potassium Osmate as a violet powder. Having recovered the majority of the Os in this way the remaining material is roasted in Chlorine to produce anhydrous IrCl3 as a prelude to porcessing the ore for the Ir. Any remaining Os is usually ignored as there is little market for it. In the case of Aqua Regia insolubles, they are fused with NaOH and Na2O2 in a 3% Nickel steel crucible at cherry-red heat for 8 to 12 hours and poured onto a cold surface to form a sheet. the sheet is dissolved in cold water which is decanted to remove the majority of the NaOH. The residue is treated with a light Aqua Regia which generates OsO4 which can be recovered by an alkaline scrubber if desired. Use of this method to recover osmium is rare and it is primarily intended to render Ir into hydrated oxides for further processing. Drrocket 19:30, 17 November 2006 (UTC)
[edit] peer reviewer output
The following suggestions were generated by a semi-automatic javascript program, and might not be applicable for the article in question.
- Please expand the lead to conform with guidelines at Wikipedia:Lead. The article should have an appropriate number of paragraphs as is shown on WP:LEAD, and should adequately summarize the article.[?]
- See if possible if there is a free use image that can go on the top right corner of this article.[?]
- Per Wikipedia:What is a featured article?, Images should have concise captions.[?]
- There may be an applicable infobox for this article. For example, see Template:Infobox Biography, Template:Infobox School, or Template:Infobox City.[?] (Note that there might not be an applicable infobox; remember that these suggestions are not generated manually)
- As per Wikipedia:Manual of Style (dates), dates shouldn't use th; for example, instead of using January 30th was a great day, use January 30 was a great day.[?]
- Generally, trivia sections are looked down upon; please either remove the trivia section or incorporate any important facts into the rest of the article.[?]
- Please reorder/rename the last few sections to follow guidelines at Wikipedia:Guide to layout.[?]
- Watch for redundancies that make the article too wordy instead of being crisp and concise. (You may wish to try Tony1's redundancy exercises.)
- While additive terms like “also”, “in addition”, “additionally”, “moreover”, and “furthermore” may sometimes be useful, overusing them when they aren't necessary can instead detract from the brilliancy of the article. This article has 8 additive terms, a bit too much.
- Please ensure that the article has gone through a thorough copyediting so that it exemplifies some of Wikipedia's best work. See also User:Tony1/How to satisfy Criterion 1a.[?]
