摘要： To produce a high-temperature superconductor of the composition Bi.sub.2 (Sr,Ca).sub.3 Cu.sub.2 O.sub.8+x having a strontium to calcium ratio of 5:1 to 2:1 and a value of x between 0 and 2, the oxides and/or carbonates of bismuth, strontium, calcium and copper are vigorously mixed in a stoichiometric ratio. The mixture is heated at temperatures of 870.degree. to 1100.degree. C. until a homogeneous melt is obtained. The melt is poured into molds and allowed to solidify in them. The cast bodies removed from the molds are annealed for 6 to 30 hours at 780.degree. to 850.degree. C. Finally, the annealed cast bodies are treated for at least 6 hours at temperatures of 600.degree. to 820.degree. C. in an oxygen atmosphere.The cast bodies can be converted into shaped bodies of the desired sizes by mechanical processes before they are annealed.The shape and size of the shaped bodies may also be determined by the shape and dimensioning of the molds used in producing the cast bodies.

摘要： A resistive current limiter takes the form of a hollow cylinder and is composed of high-temperature superconducting material. In this connection, the high-temperature superconducting material may be a polynary oxide.To produce said resistive current limiter, a homogeneous melt is prepared from an oxide mixture, suitable for forming high-temperature superconductors, in a specified stoichiometry and said melt is allowed to run, at temperatures above 900.degree. C., into a casting zone which rotates about its horizontal axis. The molding, solidified as a cylinder, is removed from the casting zone. The cylinder is sawn so as to produce a gap extending parallel to its axis. Furthermore, a multiplicity of slits are sawn into the cylinder parallel to the gap. Finally, the cylinder is heat-treated for up to 150 hours at 700.degree. to 900.degree. C. in an oxygen-containing atmosphere.
