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
