Mercury a Superconductor?

In 1911, Heike Kamerlingh Onnes, Dutch physicist and Director at the University of Leiden’s Cryogenic Laboratory, discovered that if you cool mercury to just above 4 degrees Kelvin (-269 degrees C, a few degrees short of absolute zero), mercury would exhibit almost no electrical resistance.

  • Heike Kamerlingh Onnes – Wikipedia
    Prof Heike Kamerlingh Onnes (Dutch: [ˈɔnəs]) FRSFor HFRSE FCS (21 September 1853 – 21 February 1926) was a Dutch physicist and Nobel laureate. He exploited the Hampson–Linde cycle to investigate how materials behave when cooled to nearly absolute zero and later to liquefy helium for the first time.
  • Superconductivity – Wikipedia
    Superconductivity was discovered on April 8, 1911 by Heike Kamerlingh Onnes, who was studying the resistance of solid mercury at cryogenic temperatures using the recently produced liquid helium as a refrigerant. At the temperature of 4.2 K, he observed that the resistance abruptly disappeared.

    At room temperature, the element mercury is not very magnetic at all. … In fact, superconductivity was discovered by Kamerlingh Onnes in 1911 by studying mercury at low temperatures. Superconductors generally expel magnetic fields, so you could say that below 4 K, mercury is a perfect diamagnet.
