The Meissner outcome shown by levitating a magnet earlier mentioned a cuprate superconductor, and that is cooled by liquid nitrogen Underneath some problems, including incredibly reduced temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" suggests earlier mentioned 30 K). The reason for it's not comprehended, but there are https://beckettmlkhf.dsiblogger.com/72140963/silicon-nitride-crucible-factory-things-to-know-before-you-buy
