Is LK-99 really a room temperature and atmospheric pressure superconductor as claimed by researchers from South Korea's Quantum Energy Research Center? The answer is no according to Nature's report after it underwent a peer review process by other scientists around the world.
LK-99 is produced using compounds of copper, lead, phosphorus and oxygen. But the presence of impurities in the form of copper sulphide causes LK-99 to display superconducting characteristics, which is low electrical resistance and floats in a magnetic field.
This result is certainly disappointing because efforts to find room temperature superconducting materials have been carried out for decades without any results. The superconductors used today are achieved at temperatures of -100 degrees Celsius or at extremely high pressures. Complex cooling systems make electronic devices with superconductors have a large size.
