Superconductivity at -19 ° C

Previously, it was possible to achieve superconductivity only at ultra-low temperatures close to absolute zero, but chemists do not stand still. They continue to create new experimental materials with a maximum transition temperature to the superconducting state. The new record was set on October 10, 2009 at 254 ° K, that is, around -19 ° C. Thus, it is possible to observe the effect of magnetic levitation for the first time in almost any home refrigerator.



Superconductivity is the property of some materials to have a strictly zero electrical resistance when the temperature reaches below a certain value. The phenomenon of superconductivity is used to obtain strong magnetic fields, since the passage of strong currents through the superconductor, creating strong magnetic fields, there is no heat loss.
