A fact from Phases of ice appeared on Wikipedia's Main Page in the Did you know column on 18 May 2024 (check views). The text of the entry was as follows:

Did you know... that ice in outer space is an amorphous solid, and this may be the most common phase of ice in the universe?

A record of the entry may be seen at Wikipedia:Recent additions/2024/May. The nomination discussion and review may be seen at Template:Did you know nominations/Phases of ice.

Ice XI

The article seems to contradict itself on whether the ice XI phase is hexagonal or orthorhombic. The phase diagram in the lead doesn't help, as there are two different phases labeled as ice XI. –LaundryPizza03 (d c̄) 19:01, 12 May 2024 (UTC)[reply]

I had a bit of trouble matching up the phase diagram to the table in general.

Reference 67 (https://water.lsbu.ac.uk/water/ice_xi.html) seems to be saying it's both. From what I can tell the ice is made of hexagonal layers that can be stacked in an orthorhombic fashion. https://pubs.rsc.org/en/content/articlelanding/2015/cp/c4cp02893g#!divAbstract 90.195.211.57 (talk) 23:15, 24 October 2024 (UTC)[reply]

My understanding is that Ice XI is now the low pressure, low-temperature phase. Scientists may have once believed that the next phase to be discovered after Ice X would be found by placing the latter under still greater pressure (hundreds of GPa? TPa?), hence that was called Ice XI; but the phase we now call Ice XI beat it to the punch. Olthe3rd1 (talk) 09:56, 26 January 2025 (UTC)[reply]

I have been unable to find any reference to the ultra-high-pressure state marked as "Ice XI". The <-200C/<200MPa seems well supported. Is this an accidental addition to the phase diagram that should be removed, or is it real? If the latter, please provide references. Thanks PhysicistQuery (talk)

It is criminal for this article not to make reference to…

…Kurt Vonnegut’s fictional version of Ice IX, an arrangement of water molecules packed so efficiently stable that any other water molecules it ever comes in contact with — like those in every living being on earth, instantly organize themselves into Ice IX also, leading to a chain reaction that freezes the entire world over. There could even be its own section about why the thermodynamics of this would be impossible. I think it was Cat’s Cradle where this made its appearance, but I could be wrong. 76.174.113.253 (talk) 08:44, 17 June 2024 (UTC)[reply]

Speaking of crimes of omission, your references, required by WP:VERIFY and WP:PSTS, seem to be missing. Johnjbarton (talk) 14:44, 17 June 2024 (UTC)[reply]

Discovery of ice

The "year of discovery" for regular ice is 10,500 BC? 90.195.211.57 (talk) 22:26, 24 October 2024 (UTC)[reply]

Fixed, thanks.

Done Johnjbarton (talk) 22:35, 24 October 2024 (UTC)[reply]

Thank you! We had a chuckle about that. 90.195.211.57 (talk) 22:47, 24 October 2024 (UTC)[reply]

Ice X formation mislabeled

The "Temperature Threshold" column lists Ice X as being formed from Ice III at 165 K, identical with Ice IX. This is apparently a typo. Ice X requires very different conditions from Ice IX and more likely would be formed from Ice VII or Ice VIII. Olthe3rd1 (talk) 09:52, 26 January 2025 (UTC)[reply]
