BSCCO-2223 tapes have been produced by the 'powder-in-tube' method with reproducible critical current densities of > 1 x 104 A cm-2 at 77 K and 5 x 104 A cm-2 at 4.2 K. Superconductivity at 77 K was retained in fields of up to 7 T. The influence of mechanical treatments (e.g. drawing, rolling and pr
