Note[edit]

Article changed over to new Wikipedia:WikiProject Elements format by maveric149. Elementbox converted 11:27, 14 July 2005 by Femto (previous revision was that of 22:25, 27 May 2005).

Information Sources[edit]

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Osmium. Additional text was taken directly from USGS Osmium Statistics and Information, USGS Periodic Table - Osmium, 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. Information in the main article concerning the infobox's value of Osmium's bulk modulus -- the value from a (controversial?) 2002 experimental result on osmium's compressibility -- was taken from journal articles by H Cynn et al in Phys. Rev. Lett. (original paper) and by B R Sahu et al in Phys. Rev. B (example of refutation), both of which are cited in full in the main article's References section.

Uses and Toxicity of Osmium[edit]

Uses of Osmium[edit]

- "Major uses for osmium tetroxide identified are for catalysis, especially in steroid synthesis, and for tissue staining." Osmium: An Appraisal of Environmental Exposure Environ Health Perspect. 1974 August; 8: 201–213. http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1474945

The claim that "An alloy of 90% platinum and 10% osmium is used in surgical implants such as pacemakers and replacement of pulmonary valves" is incorrect. The following reference, Chevalier, Patrick. "Mineral Yearbook: Platinum Group Metals" (PDF). Natural Resources Canada. Retrieved 2008-10-17. [dead link], is incorrect when it makes this claim; if you track down what this reference cites, you find that such alloys have been tested but there is no record of such alloys being used in actual implants.

Need to fix Hardness Units[edit]

The hardness is given in a unit that, by itself, does not fully describe how hard the material is(GPa). The author is probably referring to Vickers hardness, but I can't be sure without checking the citations. Unfortunately all of the citations are behind paywalls, so I can't confirm. Can someone with access to the cited articles correct it? Bgovern (talk) 04:49, 22 August 2017 (UTC)
