Method for producing highly textured, strip-shaped, high-temperature superconductors

Disclosed is a process for the production of a band-shaped high temperature superconductor that consists of a metal substrate, at least one buffer layer and a high temperature superconductor layer that is located on the buffer layer, the latter consisting of yttrium-stabilized zirconium oxide, gadol...

Beschreibung
Zusammenfassung:	Disclosed is a process for the production of a band-shaped high temperature superconductor that consists of a metal substrate, at least one buffer layer and a high temperature superconductor layer that is located on the buffer layer, the latter consisting of yttrium-stabilized zirconium oxide, gadolinium zirconate, yttrium oxide, lanthanum aluminate, lanthanum zirconate, strontium titanate, nickel oxide, cerium oxide, magnesium oxide, lanthanum manganate, or strontium ruthenate, comprising the steps of: (a) production of a coating solution that contains a polar solvent with at least one free hydroxyl group, (b) application of the coating solution to the metal substrate, (c) drying, (d) production of the buffer layer by annealing treatment, and (e) application of a high temperature superconductor layer on the buffer layer, characterized in that propionic acid is used as a polar solvent with at least one free hydroxyl group.
