Kinetics of Isothermal Crystallization of Amorphous PbTiO₃

Abstract

A crystallization process of amorphous samples of PbTiO₃ has been studied during 8 hours isothermal annealing at various temperatures in a vicinity of crystallization temperature T_cr = 600°C. It was revealed, that transition of amorphous material to a crystalline state is accompanied by a growth in value of its conductivity during the all time of isothermal annealing. It was established, that kinetics of isothermal crystallization may be described within the framework of the thermodynamic formalism of Kolmogorov–Johnson–Mehl–Avrami.
