Abstract:
A process for producing a current limiter having a high-temperature superconductor, the process comprising the steps of:applying to a first main surface of a silver layer a pulverulent starting material for a high-temperature superconductor;placing a second main surface of the silver layer on an inert powder layer, the second main surface being on the opposite side from the first main surface;producing a high-temperature superconductor, which forms a composite conductor with the silver layer, by conducting a heat and oxygen treatment; andapplying a mechanical stabilization layer to at least one main surface of the composite conductor;the high-temperature superconductor containing a Bi 2212 compound, andthe inert powder layer containing MgO and/or Ce.sub.2 O.sub.3 and/or SrZrO.sub.3 and/or SrSO.sub.4 and/or Y.sub.2 O.sub.3 and/or ZrO.sub.2.
