An insulated high-temperature wire superconductor includes a wire of a non-insulated high-temperature wire superconductor, the width of which is at least 10 times its thickness and in which a high-temperature superconductor is introduced into a matrix or is applied to a substrate. The wire is provided with an electrically non-conducting insulating layer on both sides such that the two insulating layers have an insulating edge width in a range from 2 mm to 200 mm which projects in relation to the wire.

High-temperature superconducting solid bodies and process for producing

Process for prorducing thallium-containing high-T.sub.c superconductors

Process for increasing the pinning force of superconducting Bi-Sr-Ca-Cu-O ceramic moldings, which comprises heating the pure-phase 2212 phase of a Bi-Sr-Ca-Cu-O ceramic molding under pure oxygen or an oxygen-containing gas for from 1 to 40 minutes to a temperature of from 825.degree. to 900.degree. C. and generating secondary-phase precipitates in the process.

Process for increasing the pinning force of superconducting

The invention relates to solid bodies made of high-temperature superconducting material to which contact is made by solid, compact metallic conductors. To produce said solid bodies, high-temperature superconducting material is either melted completely or a melt is obtained from the oxides of bismuth, strontium, calcium and copper, and, optionally, of antimony and lead. The solid, compact metallic conductors made of silver, gold, a platinum metal or an alloy containing said metals are then partially encased in the melt and the melt is allowed to solidify. Finally, the solid body obtained is annealed together with the conductors in a first stage at temperatures of from 710.degree. to 810.degree. C. and in a second stage in an oxygen-containing atmosphere at temperatures of from 750.degree. to 880.degree. C.
