The bit about compressibility tickles my mind. Really cool that some compounds maintain their structure while collapsing the space between, while others change their structure entirely when subjected to pressure. Would make for a cool visualization.
Are there theories about what structure ice-VIII, ice-IX, etc. would take?
- eesmith 9y agoFollowing the link that lamename gave about 90 minutes before your comment says that ice-VIII is tetragonal as is ice-IX. The list goes to ice-XVII. See also https://en.wikipedia.org/wiki/Ice#Phases https://en.wikipedia.org/wiki/Ice#Phases .
- Osmium 9y ago> The bit about compressibility tickles my mind. One of my favourites is 'electride' bonding, where you compress a crystal so much that the electrons get squeezed into the gaps (interstices) between atoms instead, essentially making the electrons themselves act as anions. This is really cool, and makes you wonder what other exotic high-pressure physics waits to be found. https://www.nature.com/articles/nchem.2254 https://www.nature.com/articles/nchem.2254
