Abstract

The objectives of this work were to investigate the crystallization kinetics of Yttrium Iron Garnet (Y3Fe5O12, YIG) using the thermal analysis. The Differential Scanning Colorimetric (DSC) analysis confirmed that crystallization begins to form the YIG from the nitrates of the YIG gel product at the melting temperature of 337 °C. Two weight losses were discovered from the nitrates of the YIG gel product using simultaneous thermo gravimetric analysis (TGA) and differential thermal analysis (DTA), in the temperature range of 70 to 130 °C and 760 °C, indicating the amorphous state to change the crystalline state formation. A thermo magnetization analysis (TMA) was performed on the synthesized YIG calcined at 850 °C, and the Curie temperature results were thoroughly examined. The Williamson-Hall (W-H) plots and transmission electron microscope (TEM) analysis were used to study the crystalline strain and crystalline formation of the as-prepared YIG particles at 850 °C calcined temperatures.
