Abstract: The invention relates to a process for producing a shaped body, in which a mixture of oxidic starting powders or a superconducting material, which comprises at least 30% by volume of platelet-shaped primary particles and has such a composition that a high-temperature superconducting material is formed on later, suitable thermal treatment, is comminuted by milling, shearing and/or rolling in such a way that the comminuted powder has a powder particle size distribution having a d90 of ≦20 &mgr;m, and in which the powders which have been comminuted in this way are isostatically compacted by the dry bag method.

Abstract: The invention relates to a process for producing textured high-temperature superconducting solid shaped parts, which comprises solid shaped parts made of oxide-ceramic superconducting material of a phase mixture of the substance class YBCO first being molded, pressed and sintered, a zonewise thermal treatment then being carried out along their longitudinal axis. Heating is first carried out, in a first zone, to a temperature in the range of from 50 to 200 K below the peritectic melting temperature of the phase mixture initially present in the shaped part, the temperature then is raised, in a second zone having a temperature gradient in the range of from 10 to 250 K/cm, then, in a third zone, a temperature of up to 50 K above the peritectic melting temperature of the phase mixture initially present in the shaped part is maintained, cooling then being carried out, in a fourth zone having a temperature gradient in the range of from 10 to 250 K/cm.
