Patent number: 9257628Abstract: Known processes for the production of nanoparticles of compounds of the transition metals Zr, Ti, Ta, rare earths (RE), Mn, and Fe via microemulsions lead to products that contain impurities from the reactants, particularly water, which make the further use of said nanoparticles difficult, for instance in high-temperature super conductors (HTSC). It is proposed that the nanoparticles be produced via anhydrous microemulsions having an outer phase composed of a nonpolar solvent and inner phase composed of a polar anhydrous solvent. The nanoparticles thus obtained exhibit good monodispersity and can be used in the production of REBa2Cu3O7 super conductors by incorporation into the precursor coating solution.Type: GrantFiled: March 20, 2013Date of Patent: February 9, 2016Assignee: BASF SEInventors: Thomas Freudenberg, Bernhard Holzapfel, Oliver Brunkahl, Michael Baecker

Patent number: 8513163Abstract: A high-temperature superconducting thin-film strip conductor (HTSL-CC) includes a metal substrate, a buffer layer chemically generated thereon and grown crystallographically unrotated in relation to the metal substrate, and a chemically generated superconducting coating thereon.

Patent number: 8426344Abstract: A method is proposed for producing a biaxially textured metal substrate having a metal surface, wherein the substrate is modified in order to produce a high-temperature superconductor coating arrangement and wherein the metal surface is modified in order to deposit a buffer layer or another intermediate layer epitaxially thereon and/or to deposit an oriented high-temperature superconductor (HTS) layer thereon. The method includes producing a biaxially textured metal substrate, subjecting the metal substrate surface to a polishing treatment, in particular an electropolishing treatment, and subjecting the metal substrate to a post-annealing after the surface polishing treatment and before a subsequent coating is performed involving epitaxial deposition of a layer of the HTS coating arrangement. This method results in smooth metal substrates with high textural overcoats and thereby improved HTS layers.Type: GrantFiled: November 24, 2009Date of Patent: April 23, 2013Assignee: Basf SEInventors: Michael Baecker, Matina Falter, Jan Kunert

Patent number: 8389444Abstract: A method of producing a thin layer, high-temperature superconductor strip is disclosed. In the method, a metal salt solution is formed and coated onto a substrate including a high-temperature superconductor layer. Heat is then applied directly or indirectly to the solution. The metal salt solution may contain a metal-organic salt solution or a metal inorganic metal salt solution.
