X-ray diffraction (XRD) patterns showed that Fe3O4 samples generated by these two synthesis methods are in a single phase with a cubic spinel structure. This research investigates the influence of ultrasonic irradiation in the synthesis process including size, morphology, composition and magnetic properties. The morphology of Fe3O4 was characterized by a transmission electron microscopy (TEM) instrument. The TEM image of Fe3O4 synthesized using the ultrasonic irradiation method showed a reduction of the agglomeration of the Fe3O4 particles. Moreover, the TEM images also showed that the primary particles of Fe3O4 prepared by the co-precipitation method tend to agglomerate as the particles cluster, with the particle size ranging from 9 to 33 nm. Meanwhile, Fe3O4 synthesized using the ultrasonic irradiation method tends to construct a primary particle sized about 25 to 37 nm. The magnetic properties that were characterized by vibrating sample magnetometer (VSM) measurement showed that Fe3O4 exhibited superparamagnetic behavior at room temperature.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Co-precipitation,Iron sands,Magnetite,Superparamagnetic behavior,Ultrasonic-irradiation[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]Acknowledgments –This research was partially supported by Scholarship dissertation of Lembaga Pengelola Dana Pendidikan (LPDP) and “Hibah Kompetensi” research grant of Ditlitabmas, Ditjen DIKTI, 2016.
