Abstract
Mechanical grinding and reforming process of the Pb-substituted 2223 phase has been studied for the monophasic samples with a composition of Bi0.9Pb0.2SrCaCu0.16OZ. The 2223 phase changes to ultra-fine powder by full grinding, exhibiting no magnetic response, while the ultra fine powder and the small 2223 crystals coexist in samples ground for short periods. Some second phases were formed in the ground powder subjected to heating at temperatures between 500°C and 800°C. On the other hand, annealing of the bulk samples below 800°C leads to precipitation of the 3321 phase identified as Sr2.5Bi0.5Pb3Ca2CuOZ. Precipitation of second phases in the coexistent powder was interpreted by those in ultra-fine powder and bulk samples.
