Abstract

We have fabricated BSCCO 2223 by modified two powder process and investigated 2223 phase formation and grain growth. Phase evolution and reactivity of 2223 were remarkably sensitive to size of 2212 grains and liquid phase. Larger size of 2212 phase increased liquid formation temperature. The Avrami relation was well suited for describing the kinetics of grain growth in BSCCO 2223.
