Influence of iron ferrite nanoparticle characteristics by stirring methods in co-precipitation production process

Fe3O4 nanoparticles were generated by chemical precipitation process. In order to assess the result of stirring process on the nanoparticles properties, two types of stirrings (mechanical and magnetic) were used. Oleic acid covered the nanoparticles as surfactant performer. Vibrating sample magnetometer (VSM) examined the magnetic characteristic of the nanoparticles. Hysteresis loop characterized the magnetic nanoparticles. X-ray diffraction (XRD) investigated the fine grains sample. The XRD diagrams show the presence of the most powerful apexes fit to the orientations of crystal surfaces of the spinel form of the nanoparticles. The average dimensions of the nanoparticles was evaluated by Scherrer approximation. The mean particle dimensions were 11nm (chemical mixer) and 13nm (magnet mixer). The scanning electron microscope (SEM) images verified the spherical shape of the nanoparticles. Fourier transform infrared spectroscopy (FTIR) confirmed the constitution of Fe-O bonds and validated the spinel ferrites configuration.
