Abstract: A superconducting multilayer ceramic substrate is disclosed, prepared by firing a laminate of at least two polymer bonded cast sheets of a ceramic dielectric oxide powder, at least one sheet of which has a metallization pattern provided thereon, to thereby form a superconducting oxide reaction layer at the interface between the sintered ceramic material and the embedded metallic conductor lines of the metallization pattern.

Abstract: Compositions having the formula A1+/-xM2+/-xCu3Oy, wherein A is Y, or a combination of Y La, Lu, Sc or Yb; M is Ba, or a combination of Ba, Sr or Ca and y is sufficient to satisfy the valence demands, have been found to be bulk electrical superconductors at a temperature above 77K. The compositions are single phase perovskite-like crystalline structures. They are made by a process involving intimately mixing the metal oxides or their precursors in the proper molar ratios, heating the mixture in the presence of oxygen to a temperature between about 800 DEG C and about 1100 DEG C and slowly cooling the mixture to room temperature in the presence of oxygen over a period of at least four hours.
