    摘要： A superconducting structural body comprising an oxide based superconducting ceramics powder having a perovskite structure and a metal sheath surrounding the oxide based superconducting ceramics powder, the metal sheath including an Ag portion and a non-Ag metal portion, the Ag portion existing from the inner to outer surfaces of the metal sheath, a superconducting ceramics powder portion existing in the structural body, the non-Ag metal protion used as a structural material of the metal sheath of an outermost layer of the structural body, the superconducting ceramics powder portion and the non-Ag metal portion being disposed so as to be indirectly contact each other through the Ag material, and the superconducting structural body having a compressed oriented layer in which the C-axis of the crystal in the superconducting ceramics powder is oriented in the direction perpendicular to the longitudinal direction of the superconducting structural body, and in which a thickness thereof is not smaller than 5 .mu.m, and a process for fabricating the superconducting structural body. The superconducting composite wire and cable according to this invention each have effects that the content of Ag, which is very expensive, can be reduced compared to that needed in the conventional wire and cable, that they have excellent strength at a high or room temperature, that they have high critical current density, and they can be produced at ease.

    摘要： A process for fabricating worked superconducting ceramic material of a mean grain size not more than 10 um is disclosed, which comprises the steps of: (a) preparing a metal casing containing a starting powder material having a composition for forming an oxide superconductor; (b) calcining the starting powder material contained in the casing at a temperature range of 850.degree. to 950.degree. C.; (c) subjecting said casing to a HIP treatment; (d) subjecting said casing containing hot deformed material to cold deformation processing; and (e) subjecting said casing to stress relief treatment by annealing in the presence of oxygen.
