Abstract
Effects of an intermediate press process on the microstructure and superconducting properties of the Pb-doped Bi-Sr-Ca-Cu-O system have been studied. Samples were made by sintering uniaxially pressed pellets after the conventional pellet-sintering process. Highly textured microstructure with strong (001) reflections was confirmed by X-ray diffraction and SEM. A short sintering time was sufficient to form only the high-T c phase. By this intermediate pressing and sintering process, J c was much increased and the magnetic field dependence of J c was also improved. The highest J c achieved was 3560 A/cm2 at 0 T and 77.3 K.Keywords
