A simple and low-cost method for producing a thin film of ribbon-like oxide high-temperature (high-Tc) superconductor, which comprises placing a solid starting material for the oxide high-temperature superconductor on a substrate and heating it at a temperature in the vicinity of the melting point of the solid starting material under ambient pressure in an oxygen atmosphere.

Method for producing thin films of ribbon-like oxide high-temperature superconductor

In a process in which a composite consisting of a metallic base and a superconductor mainly containing a Bi,Sr,CaCu,O,superconducting phase is formed into a composite wire or wire, the composite is subjected to calcination and cold working before heat treatment for crystallization from a partial molten state.
