Abstract: 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.

Abstract: The invention relates to a method for producing a composite comprising a high-temperature superconductor (HTS) layer based on rare earth metal-barium-copper oxide on a substrate with defined biaxial texture, having the following steps: applying a first HTS coating solution to the substrate, drying the first HTS coating solution to produce a first film, pyrolyzing the first film to produce a first pyrolyzed sublayer, removing an interfacial layer on the upper side of the first pyrolyzed sublayer to produce a first pyrolyzed sublayer with reduced layer thickness, applying a second HTS coating solution to the first pyrolyzed sublayer with reduced layer thickness, drying the second HTS coating solution to produce a second film, pyrolyzing the second film to produce a second pyrolyzed sublayer, optionally forming one or more further pyrolyzed sublayers on the second pyrolyzed sublayer, and crystallizing the overall layer formed from the pyrolyzed sublayers to complete the HTS layer, wherein the removal of the interfacial layer in step D) is effected in such a way that a texture determined by the defined biaxial texture of the substrate is transferred to the first and also to the second pyrolyzed sublayer, and also to a product producible by such a method.

Abstract: The present invention relates to a precursor (1) for production of a high-temperature superconductor (HTS) in ribbon form, comprising a metallic substrate (10) in ribbon form having a first ribbon side (11) and a second ribbon side (12), wherein, on the first ribbon side (11), (a) the substrate (10) has a defined texture as template for crystallographically aligned growth of a buffer layer or an HTS layer and (b) an exposed surface of the substrate (10) is present or one or more layers (20,30) are present that are selected from the group consisting of: buffer precursor layer, pyrolyzed buffer precursor layer, buffer layer, HTS precursor layer, pyrolyzed HTS buffer precursor layer and pyrolyzed and further consolidated HTS buffer precursor layer, and, on the second ribbon side (12), at least one ceramic barrier layer (40) that protects the substrate (10) against oxidation or a precursor which is converted to such a layer during the HTS crystallization annealing or the pyrolysis is present, wherein, when one or more layers (20, 30) are present on the first ribbon side (11), the ceramic barrier layer (40) or the precursor thereof has a different chemical composition and/or a different texture than the layer (20) arranged on the first ribbon side (11) and directly adjoining the substrate (10). In this precursor, the barrier layer (40) is a layer that delays or prevents ingress of oxygen to the second ribbon side (12) and is composed of conductive ceramic material or a precursor which is converted to such a precursor during the HTS crystallization annealing or the pyrolysis, and the ceramic material is an electrically conductive metal oxide or an electrically conductive mixture of metal oxides, wherein the conductive metal oxide or one or more metal oxides in the conductive mixture is/are preferably metal oxide(s) doped with an extraneous metal.
