Ceramic superconductors ppt.
Superconductivity basic phenomenon if a material is described as a superconductor below a certain temperature the critical temperarure it loses its electrical resistivity to become a perfect conductor.

T boiling point for he 4 2k study of properties of metals at low t.
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.

Yba 2 cu 3 o 7 x was the first ceramic superconductor discovered with t c greater than liquid nitrogen temperature.
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.
