LK-99 isn’t a superconductor
Summary: Researchers have debunked claims that LK-99 is a room-temperature superconductor, revealing that impurities, particularly copper sulfide, were responsible for its superconducting-like properties. The material, a compound of copper, lead, phosphorus, and oxygen, was initially believed to be the first superconductor to work at room temperature and ambient pressure. However, after numerous replication efforts, experts have concluded that LK-99 is not a room-temperature superconductor.
