Ceramic superconductor applications.

The importance of the work of bednorz and müller was that their discovery of superconductivity in ceramics with a perovskite like structure that led directly to superconductivity above liquid nitrogen temperatures. This superconductor has a critical transition temperature around 90k well above liquid nitrogen s 77k. Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic flux fields are expelled from the material. Humphreys in concise encyclopedia of advanced ceramic materials 1991.

This chapter discusses the theory crystalline structure properties and applications of ceramic superconductors. Chemical formula is yba2cu3o7. The temperature at which resistance ceases is referred to as the transition temperature or critical temperature tc. The ceramic materials used to make superconductors are a class of materials called perovskites.

The superconductor we will be experimenting with is an yttrium y barium ba and copper cu composition. Any material exhibiting these properties is a superconductor unlike an ordinary metallic conductor whose resistance decreases gradually as its temperature is lowered even down to near absolute zero a superconductor has a. Superconductivity is the complete disappearance of electric resistance in materials that are cooled to extremely low temperatures. Conductive ceramics conductive ceramics superconductors.
