HGBACACUO SUPERCONDUCTORS - PROCESSING, PROPERTIES AND POTENTIAL

HgBaCaCuO superconductors exhibit superior superconducting properties especially at temperatures above 77 K. Irradiation studies have proven that there is a great potential even for further enhancements. Progre ss in the synthesis of Hg-based superconductors has been achieved by t he development of a two-zone technique, which has opened the window fo r applying a variety of materials processing techniques successfully u sed in other high temperature superconductors. HgBaCuO-silver composit es have been prepared by the powder in tube method and reacted in the two-zone assembly. Silver, which has successfully been used as sheath material for most other high-T-c superconductors, appears to be compat ible with superconductors of the HgBaCaCuO family.
