No; it's claimed to superconduct at temperatures up to 127 °C. They didn't perform tests above 127 °C.
- mbauman 3y ago> They didn't perform tests above that temperature. Right, exactly, they're claiming that Tc is above 127°C. The claim is that it's a superconductor at (some) temperatures even higher than what was tested. It's also still a superconductor at temperatures below.
- croes 3y agoI was puzzled by that sentence. I wouldn't call 127°C room temperature.
- philwelch 3y agoAll of the known, confirmed superconductors only work at extreme cryogenic temperatures.
