LK-99 is a supposed superconductor that can operate at ambient atmospheric press and below temperatures of 127°c/260°f. In other words, a room-temperature superconductor. The holy grail of conductors. A material that’d completely revolutionize literally everything. Not only that, it’s made out of a lead-apatite, meaning it would potentially be relatively inexpensive to make. We could be on the edge of a new era.
AND HERE COMES THE BUTT
BUT my understanding is that attempts to replicate the experiment are currently inconclusive. There have supposedly been successful replications as well as unsuccessful attempts, however none of the papers have been peer reviewed yet. Additionally, computer simulations have given inconsistent results.
