High-temperature superconductors, which are almost always some type of cuprate ceramic doped with a variety of elements, conduct electricity with near-zero resistance at temperatures as high as -226 F.

High-temperature superconductivity in compounds of copper, oxygen and other elements were discovered in 1986 by Swiss scientists, Georg Bednorz and Alex Mьller. Both scientists were awarded the 1987 Nobel Prize in physics "for their important break-through in the discovery of superconductivity in ceramic materials."
