Fabrication and Characterization of Yttrium Barium Copper Oxide Superconductors for Microwave Applications

reportActive / Technical Report | Accession Number: ADA231713 | Open PDF

Abstract:

High temperature superconductors offer several advantages over normal conductors for low power device applications. Bulk ceramic processing parameters are investigated to define optimum conditions for materials useful in microwave applications. Calcining, sintering, and reaction atmosphere were systematically varied in bulk samples. The density, microstructure and composition, dc resistivity, microwave Q, and surface resistivity were followed as a function of sintering temperature. An optimum sintering temperature is defined.
