BSCCO superconductors

Patent Pending Bismuth strontium calcium copper oxide, or BSCCO (pronounced "bisko"), is a family of high-temperature superconductors having the generalized chemical formula Bi2Sr2Can-1CunO2n+4+x, with n=2 being the most commonly studied compound (though n=1 and n=3 have also received significant attention). Discovered as a general class in 1988,[1] BSCCO was the first high-temperature superconductor which did not contain a rare earth element.
