A method of making a ribbon-like or sheet-like superconducting composite body is disclosed. The method is well suited for making long lengths (e.g., >100m) of ribbon or large areas (e.g., >100cm2) of sheet-like composite. The method comprises forming a Bi-Sr-Ca-Cu-oxide-containing layer on a metal (exemplarily Ag) substrate, and mechanically deforming (typically by rolling) the thus formed composite such that the oxide is densified to more than 80% of the theoretical density. Subsequently the oxide layer is at least partially melted and allowed to re-solidify such that a large portion of the oxide crystals has c-axis alignment. After appropriate heat treatment in an O2-containing atmosphere, thus produced superconductor ribbons or sheets can have high Jc ( 104, frequently > 105 A/cm2) for temperatures less than about 20K and in magnetic fields less than about 5T.
