Abstract
In this study, iron oxide nanoparticles (IONPs) were synthesized via explosion of ST37 wires with various diameters in distilled water. Synthesized IONPs were studied by XRD, UV_ visible, FE_SEM, EDS and VSM analyzes. The XRD results showed that the produced powders are magnetite (Fe3O4) with cubic structure. The UV–visible results confirmed the results of the XRD and the presence of magnetite by showing the peak in the 200 nm range. FE_SEM results revealed that synthesized IONPs were spherical in shape. According to XRD and FE_SEM results, with increasing in the wire diameter, the size of nanoparticles was increased and as a result, the saturation magnetization was also increased.
