A stabilized, ceramic high-temperature superconductor based on molten metal oxides is specified, which is characterized in that a metallic conductor, preferably made of noble metal, is guided parallel to the high-temperature superconductor, the high-temperature superconductor being in contact with the metallic conductor .n n n The ceramic high-temperature superconductor stabilized according to the invention is produced by arranging one or more metallic conductors in a matrix parallel to the longitudinal axis of the matrix and the matrix with melted metal oxides of bismuth, strontium, calcium and copper in a molar ratio of metals of 2: 2: Filled 1: 2 and allowed to solidify, the solidified melt was taken from the die and tempered in a first stage at temperatures of 710 to 810 ° C and in a second stage in an oxygen-containing atmosphere at temperatures of 750 to 870 ° C. |
