Abstract

The kinetics of (Bi,Pb)₂Sr₂Ca₂Cu₃O_10+x phase formation in KCl flux was studied, and kinetic analysis using the Avrami relation for isothermal phase transformation gave the Avrami exponent n = 2.5 at 855°C for the whole process of (Bi,Pb)-2223 phase formation. The estimated value of the activation energy E_a = 150 kJ/mol for the formation of (Bi,Pb)-2223 phase at 845-855°C is the lowest among the previously reported values. The low value of activation energy explains the fast formation of single-phase (Bi,Pb)-2223 powder in the KCl flux.
