| 摘要 |
The invention relates to a method for producing high temperature superconductors having at least one transformed metal oxide superconducting layer made of an initial material, comprising the following steps: the initial material for the superconducting layer is disposed on a strip-like base, especially a metal strip, and the initial material is transformed into a superconducting layer by controlled heat treatment steps comprising melting and cooling. The invention more specifically relates to the production of coated high-temperature conductors. Foreign elements are introduced in various concentrations, enabling an uneven melt point to be maintained over the cross-section of the strip, enabling specific crystal growth to be triggered, assisted, promoted, maintained and/or controlled during the heat treatment steps, especially during cooling. As opposed to methods known per se, specific crystal growth is initiated, maintained, promoted and controlled for the formation of a mono-crystalline or polycrystalline arrangement in the superconducting layer by means of inward transfer, diffusion or mixing with foreign elements of various concentrations and, consequently, a solid-liquid interface is formed along the cross-section of said strip.
