Abstract

A description is given of a solid oxide-ceramic superconductor containing copper in the crystal lattice which is composed of crystals which are arranged essentially in parallel and intergrown with one another and which also contains, per 100 g of copper in the superconductor, 0.04 to 0.5 mol of CuF.sub.2 or KF, and of a sinter process for producing it. The copper-containing superconductor may be made up, for example, of bismuth, strontium, calcium or of bismuth, strontium, calcium, lead and also copper and oxygen.
