extremely high pressures change #chemistry as we know it, such as totally screwing with #electronegativity, and thus bonding and conductivity properties: https://phys.org/news/2022-03-weird-world-high-pressure-chemistry-simple.html

this in turn allows the formation of such unusual compounds such as compounds of #lithium and #cesium, which may be useful #superconductors when cooled:
