New high temperature superconducting record: LaH10 at -23C and 170 GPa
- Zanni 8y agoThat parenthetical caveat about the pressure is a doozy. 170 gigapascals is almost 1.7 million atmospheres. So, yes, that's "warmer than the current temperature at the North Pole," but not remotely close to conditions you can easily achieve at the North Pole. For contrast, the crush depth of a modern nuclear submarine is about 3,000 feet, with pressure of less than 100 atmospheres. Kudos to OP for including it in the post title.
- jnurmine 8y agoHow does one go about creating this kind of crazy pressure...?

- 0db532a0 8y agoDoes anyone know why such high pressures are needed? Does the material adopt a different sort of crystalline structure at that point?
- avmich 8y agoThere were recently reports about room-temperature of H2S superconductor under insane pressures. You can hold some big pressures of material formed as thin cylinder with thick walls of composites, but I'm not sure about actual numbers.
