The Meissner Effect shown by levitating a magnet earlier mentioned a cuprate superconductor, and that is cooled by liquid nitrogen Under some conditions, including very reduced temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" usually means earlier mentioned 30 K). The main reason for this is not recognized, https://augustjmkig.azzablog.com/39581616/top-guidelines-of-ceramic-coating-process
