BSCCO
BSCCO, or bismuth strontium calcium copper oxide, refers to a family of cuprate high-temperature superconductors in which copper oxide planes carry the superconducting current. The most studied members are Bi2Sr2CuO6 (Bi-2201), Bi2Sr2CaCu2O8 (Bi-2212), and Bi2Sr2Ca2Cu3O10 (Bi-2223). Tc values depend on phase and doping: roughly Bi-2201 20–30 K, Bi-2212 85–95 K, and Bi-2223 110–120 K, with higher values achieved under optimal oxygenation and cation ratios. These materials superconduct at temperatures well above the boiling point of liquid nitrogen, classifying them as high-temperature superconductors.
BSCCO compounds have a layered crystal structure based on CuO2 planes separated by bismuth oxide and alkaline-earth
Preparation typically involves solid-state synthesis from precursor oxides and carbonates, followed by high-temperature sintering, slow cooling,
Applications of BSCCO include high-field magnets, power transmission conductors, and research devices. While practical deployment is
