LK-99

LK-99 is a potential room-temperature superconductor with a gray‒black appearance.: 8 It has a hexagonal structure slightly modified from lead‒apatite, by introducing small amounts of copper. The material was first discovered and manufactured by a team of researchers including Sukbae Lee (이석배) and Ji-Hoon Kim (김지훈) from Korea University.: 1 The team claims it functions as a superconductor at ambient pressure and below 400 K (127 °C; 260 °F).: 1 As of 2 August 2023, the material has not been confirmed to be superconducting at any temperature. The synthesis of LK-99 and observation of its superconductivity have not been peer reviewed or independently...
