Study of Crystallization Kinetics of Amorphous Zirconia in Fe₂O₃ Matrix by Kissinger Method

Abstract:

The composite materials Fe₂O₃-ZrO₂ with different content of zirconium oxide have been obtained by thermochemical synthesis. The process of crystallization of zirconium dioxide and the effect of the amount of zirconium dioxide on the phase transformation have been studied by DTA and microscopy. The activation energy of the crystallization process was calculated by the Kissinger method to be in average 170 KJ/mol. It is shown that an increase of the ZrO₂ content leads to an increase of temperature of crystallization.
