Refining behavior of the Pb-substituted Bi-2223 phase through mechanical grinding and thermal behavior of its ground powder on heating in air have been examined for samples with a nominal composition of Bi1.8Pb0.4Sr2Ca2Cu3.2Oz by XRD, DTA, SEM, TEM, ED and magnetic measurements. The 2223 phase easily changes into superfine powder by mechanical grinding. On annealing the ground powder below 800°C, various second phases were formed, while at 850°C the 2223 phase was reformed depending upon the amount of the superfine powder in the samples.
