The crystallization kinetics of Y2Ti2O7 powders prepared by a Pechini-type polymerized complex route was studied using differential thermal analysis under non-isothermal conditions. Apparent activation energies of crystallization of 816 and 804 kJ mol(-1) were obtained from calculations based on the Arrhenius equation and isoconversional analysis, respectively. The crystallization kinetics followed the so-called A3 model, as confirmed using several criteria, namely, the Malek, master plot, and Perez-Maqueda Methods. The measurement results and calculated crystallization parameters (n = 3, m = 2) showed that the crystallization process includes a constant rate of nucleation and two-dimensional growth of nuclei, and excluded the possibility of surface crystallization.
