Abstract  

Crystallization behaviour of the amorphous Bi0.96Pb0.24SrCaCu1.6O5+x (0<x<1), obtained by rapidly quenching the melt, has been investigated by the differential thermal analysis (DTA) method under different atmosphere e.g. Ar, air, O2 and vacuum. Crystallization temperatures, activation energies and heat of crystallization are found to be 708–728 K, 2.25–2.32 eV and 0.16–1.81 kJ/g-atom, respectively, depending upon the atmosphere used during DTA. This material undergoes a number of structural and thermochemical transformations on continuously heating during DTA upto the melting temperature, which depends critically upon the atmosphere used.
