Abstract
An oxide superconductor article having an oxide superconductor layer of a predetermined pattern is prepared by continuously advancing a wire having a textured surface into a deposition zone, dispensing droplets of a precursor solution to an oxide superconductor from a reservoir and the depositing droplets onto the textured surface of the wire that is introduced into the deposition zone, heating the wire or tape in the reaction zone under conditions to convert the precursor solution into an oxide superconductor; and collecting the wire after heating.
Claims15
A method of preparing a superconducting article, comprising:
- a. providing a precursor solution comprising precursor components to a rare earth-alkaline earth metal-transition metal oxide solubilized in one or more solvents;
- b. depositing the precursor solution as droplets onto a target surface in a pre-determined pattern, said target surface comprising a textured surface of a wire, wherein the precursor solution is deposited to form an array of filaments extending substantially continuously along the length of the wire;
- and
- c. converting the deposited precursor solution into an oxide superconductor.
