Crystallization behavior of Bi1.25Y1.75Fe5O12 prepared by coprecipitation process

A non-isothermal study of the crystallization kinetic of coprecipitation of Bi1.25Y1.75Fe5O12 was carried out by differential scanning calorimetry (DSC). The Avrami exponent n suggesting the dimensionality of crystal growth was determined using the Ozawa equation. From non-isothermal DSC data presented values in range of 775–1023 kJ/mol and 3.28–2.10 for the activation energy of crystallization and the Avrami exponent, respectively. These Avrami exponent values were consistent with surface and internal crystallizations growth simultaneously.
