Ceramic Superconductors Ppt

Crystal structures of high temperature ceramic superconductors the structure of high t c copper oxide or cuprate superconductors are often closely related to perovskite structure and the structure of these compounds has been described as a distorted oxygen deficient multi layered perovskite structure.

Superconductor ceramics is the property of its rightful owner. Yba 2 cu 3 o 7 x was the first ceramic superconductor discovered with t c greater than liquid nitrogen temperature. Superconductors are the material having almost zero resistivity and behave as diamagnetic below the superconducting transiting temperature superconductivity is the flow of electric current without resistance in certain metals alloys and ceramics at temperatures near absolute zero and in some cases at temperatures hundreds of degrees. The ceramic materials used to make superconductors are a class of materials called perovskites.
