✦ Synopsis

Dense Bi2223 superconductors have been successfully formed by hot stacking-forging process (HSF). Neutron diffraction measurements were used to investigate the bulk textures of HSF-Bi2223 samples. Angular dependence of transport critical current density, J c values were measured at various temperatures and different applied magnetic fields. Several textured pieces were hot-stacked. This procedure leads to an increase of both the sample thickness and the nominal engineering critical current (I c ), favourable hints for use of textured-Bi2223 in power generation supplies.

We have optimized a texturing process of Bi-Pb-Sr-Ca-C'u-O (2223) superconducting ceramics by hot pressing. The Hoechst precursor powder has been first pressurized at 1 GPa and then heated under uniaxial stress up to 35 MPa, just below the melting temperature between 850°C and 857°C. We have obtaine
