High-Temperature Ceramic Superconductors
Abstract
The principle goals of this program were (1) to demonstrate fabrication of high-temperature ceramic superconductors via a sol gel method that can operate at or above 90K with appropriate current density, J sub c, in forms useful for application in resonant cavities, magnets, motors, detectors, computers, and other devices; and (2) to fabricate and demonstrate selected components made of these materials, Including microwave cavities and magnetic shield. The approach is to develop the sol gel technology processing of high- temperature ceramic superconductors to make sol gel a viable process for fabricating high T sub c (90 K) superconductors in forms useful for applications,. The nature of sol-gel processing makes it inherently amenable to fabricating the thin films and fibers that are needed for many applications. In addition, the relatively low temperature characteristics of sol-gel processing make it advantageous for many applications in which the superconducting materials must be applied to heat sensitive substrates.
