Ceramic Superconductor Applications

The superconductor we will be experimenting with is an yttrium y barium ba and copper cu composition.

Ceramic superconductor applications.

The first high temperature superconductor was discovered in 1986 by ibm researchers bednorz and müller 3 6 who were awarded the nobel prize in physics in 1987 for their important break through in the discovery of superconductivity in ceramic materials. Conductive ceramics conductive ceramics superconductors. Chemical formula is yba2cu3o7. 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.

The temperature at which resistance ceases is referred to as the transition temperature or critical temperature tc. Many ceramic superconductors physically behave as superconductors of the second type. The ceramic materials used to make superconductors are a class of materials called perovskites. 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.

Humphreys in concise encyclopedia of advanced ceramic materials 1991. This chapter discusses the theory crystalline structure properties and applications of ceramic superconductors. Tc is usually measured in degrees kelvin k 0 k being absolute zero the. Superconductivity is the complete disappearance of electric resistance in materials that are cooled to extremely low temperatures.
