Fe3O4 nanoparticles as additives for gamma-ray shielding: Structural and surface characterization

Abstract

Monodisperse samples of magnetite nanoparticles in the size range of 5-13nm, were prepared by solvothermal synthesis and coprecipitation method. Obtained nanoparticles were characterized by different measurement techniques: X-ray diffraction analysis, transmission electron microscopy, selected area electron diffraction measurement, and Fourier transform infra-red spectroscopy. Measurements confirmed that the utilized synthesis methods are able to produce size and shape-controlled nanoparticles of a high-quality, that is of the technological importance. The results of the performed study represent the first stage in preparation of the Fe3O4 nanoparticles as an additive to concrete, which will be used for the construction of the special military facilities where it is necessary to provide a protection against γ-ray radiation.
