Abstract
Ceramic dielectric substrates, calcium titanate, bismuth titanate and strontium titanate, used with superconductor, Ytrium Barium Copper Oxide, or YBC, as an electrode, produce a superconducting electrical device, useable as a filter or capacitor. The electrical device formed by using one of the dielectrics taught herein in combination with YBC, is mechanically stable in comparison to prior art ceramic dielectrics that used YBC for an electrode material, in that the YBC is substantially free of microcracks and remains bonded to the substrates.
