In 1913, it was discovered that lead became superconducting at 7.2 K. It was then 17 years until niobium (Nb) was to superconduct at higher temperature 9.2 K. The highest known temperature T at which a material went superconducting increased slowly as scientists found new material with higher value of T, but it was in 1986 that a …
