ABSTRACT:
Disclosed here is a shaped article superconductor comprising platelets of superconducting oxide crystals which are normally anisotropic but in which said anisotropy is reduced by joining together the oxides superconductor crystallites with a normally conductive metal layer interposed therebetween. The separation distances of the platelets are, on the average, less than the coherence length of the normally conductive metal under conditions which render the oxide crystals superconductive.
