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.

Processes for the fabrication of MgBpowder and wires are provided. Powders are produced by mechanically alloying magnesium- and boron-containing precursors under controlled conditions to avoid secondary phase and impurity formation. Powders are also prepared by vapor phase reaction of volatile magnesium- and boron-containing precursors. Wires, tapes, films and coatings are provided.
