摘要：

The phase formation kinetics of the Bi,Pb(2223) phase in powders with two different nominal compositions has been studied. An analysis of the Bi,Pb(2223) phase evolution using the Avrami relation for isothermal phase transformations revealed a two-stage process with a marked change of the n-exponent during the course of the Bi,Pb(2223) phase formation after about 12 h sintering. The activation energy for this formation and the value of the Avrami exponent were found to be related to the extent of partial melting occurring in the precursor powders.
