Abstract: The invention relates to a method for coating shaped bodies made of a superconducting material based on (Y/SE)BaCuO. The invention is characterized in that a coating consisting of a coating material is applied to at least one part of a surface of the shaped body, whereby the coating material at least partially melts at a lower temperature than that of the material of the shaped body and/or is flowable at a lower temperature than that of said material. The shaped body with the applied coating material is heated to a temperature at which the material of the shaped body does not yet melt and/or is not yet flowable, however at which the coating material is at least partially melted thereon and/or is in a flowable state.

Abstract: Protected superconductor component and process for its production The invention relates to a high-temperature superconductor component with a particular cross-sectional area, which has a current-carrying section, the current-carrying section being in contact with a safety conductor in such a way that the critical current flowing on transition of the superconductor to normal conduction can be taken up without damage by the safety conductor in at least 1 second and rerouted, as well as a process for its production.

Abstract: A method of curing cracks in a ceramic shaped body made from ceramic magnet materials or ceramic superconductor materials, in which a filling material which melts at a lower temperature than the material of the shaped body or is flowable at a lower temperature than the material of the shaped body is applied to the surface of the shaped body at least in the area of a crack and/or is introduced into at least one crack, in which the shaped body with the filling material is heated to and maintained at a temperature at which the material of the shaped body does not yet melt or is not yet flowable, but at which the filling material is in at least partially molten and flowable state at least until the fused filling material can penetrate at least partially into the crack, in which the filling material consists of non-metallic or essentially of non-metallic compounds and is at least partially crystallized, and in which the shaped body with the filling material is cooled, wherein the thermal crystallization conditions
