High-temperature superconductor in wire or strip form, based on a superconducting ceramic of the class (La, Ba, Sr)2CuO4 or of the class (Y, RE)Ba2Cu3O6.5+y, with RE = rare earth and 0 y 1, and a mechanical support and a normal conductor

摘要

High-temperature superconductor in wire or strip form, based on a superconducting ceramic (3) of the class (La, Ba, Sr)2CuO4 or of the class (Y, RE)Ba2Cu3O6.5+y, with RE = rare earth and 0 y 1, consisting of a flexible support (1) made of metal or ceramic which is arranged inside or on one side of the superconducting ceramic (3), a barrier layer (2) which at least partially encloses the support, the superconducting ceramic (3) itself, which is fixed on the barrier layer and carries an intermediate layer (4) as a diffusion barrier or protective layer, and a coat (5) consisting of insulating material and providing an all-round seal.
