[edit]A gas with a density twice that of water? I don't think it's right, especially considering the density of SF6 and TeF6. I believe it's a typo. —Preceding unsigned comment added by 62.194.16.188 (talk) 22:11, 3 November 2010 (UTC)
- Sure, it must be solid (or liquid density), will fix soon. Materialscientist (talk) 22:19, 3 November 2010 (UTC)
Wrong boiling point
[edit]Boiling point cannot be lower than melting point. --83.5.152.151 (talk) 09:01, 1 April 2020 (UTC)
- The CRC Handbook of Chemistry and Physics says that selenium hexafluoride does not have a normal melting point since the triple point is above 1 atmosphere. I think in this way it is similar to carbon dioxide. The selenium hexafluoride infobox does not make this clear though, and should be modified to something more like the carbon dioxide infobox.

Toxic but inert?
[edit]Anyone know how it can be inert but still listed as a toxin. By contrast SF6 is not toxic. Ender's Shadow Snr (talk) 08:15, 23 July 2022 (UTC)
- Very good point. Three thoughts: 1) all things are relative. 2) Many would-be editors of chemistry pages dont know enough chemistry to contribute anything but safety warning from MSDS's. 3) it doesnt matter because this stuff is so esoteric. --Smokefoot (talk) 13:21, 23 July 2022 (UTC)
- Indeed the medical reference claims that it is corrosive to mucoses because it hydrolyzes in contact with moisture; whereas the article claims that it resists hydrolysis even in 10% NaOH. The reference for the latter is a textbook that is not available online. I wonder if someone confused SeF6 with SF6? --Jorge Stolfi (talk) 20:10, 12 November 2024 (UTC)
