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., 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.

Anybody care to take a stab at a less opaque wording than "This reaction is thermodynamically favorable at room temperature" in the final paragraph? rowley (talk) 12:53, 16 September 2023 (UTC)

I agree that "thermodynamically favorable" is not familiar terminology to the average reader, but it has a specific chemical meaning that is covered at the high school level. The term is also used in other chemistry articles, such as the one on diamonds. SpugoV (talk) 04:45, 29 December 2023 (UTC)

The elastic modulus (E) of Osmium is missing from this page but it is known to be 560 gigapascals. This can be found in textbooks such as "Ultra-High Temperature Materials I" by Igor L. Shabalin. Is there a reason it is missing or can someone add it? Berksoykan (talk) 21:46, 14 May 2024 (UTC)

Please add it with that reference like:
Shabalin, Igor L. (2014). "Osmium". Ultra-High Temperature Materials I. Dordrecht: Springer Netherlands. pp. 359–386. doi:10.1007/978-94-007-7587-9_5. ISBN 978-94-007-7586-2.

can someone add further clarification to the quote that Osmium tetroxide smells strongly of Osmium tetroxide as it does not clarify much of anything Jeb12321 (talk) 16:15, 24 March 2025 (UTC)
