摘要

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 (Fe_3O_4) 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 FESEM results, with increasing in the wire diameter, the size of nanoparticles was increased and as a result, the saturation magnetization was also increased.
