Abstract

Thermal behavior of the Bi-2223 phase in the Bi, Pb-Sr-Ca-Cu-O system, especially segregation and dissolution reaction of the '3321' phase which was identified as Sr2.5Bi0.5Ca2CuOz, has been studied by XRD, SQUID and resistivity measurements. On annealing below 830°C in air, the '3321' phase precipitated from the 2223 crystals. When the 2223 phase was annealed at 750°C in O2 stream, the precipitation of the '3321' phase increased. On annealing at 750°C in Ar stream, however, no precipitation of the '3321' was detected. By reheating at 850°C even for 1 min, the '3321' phase was almost dissolved into the mother 2223 crystals.
