  • Process for the production of highly-textured, band-shaped, high-temperature superconductors
    Patent number: 7763569
    Abstract: A wet-chemical method for producing strip-shaped high-temperature superconductors with a substrate, optionally with a buffer layer and with a high-temperature superconductive layer is improved by increasing the texturing and the layer thickness of the high-temperature superconductive layer. To this end, precursor solutions are applied in layers to the substrate, of which the first is low in fluorine or does not contain fluorine, and the following have a fluorine concentration that increases with each layer.
