Abstract
Transmission electron microscopy (TEM) with electronic diffraction and X-ray diffraction (XRD) was
used to study structural features of nanosized magnetite Fe3O4, which was synthesized using polymeric
matrices (polysaccharide chitosan, at alias). From the received data it was revealed that growth inhibition
and size stabilization of Fe3O4 nanoparticles were strongly affected by polysaccharide matrix. It was also
observed that directional size decrease of Fe3O4 nanoparticles was accompanied by the increasing defectiveness
of crystal lattice and decreasing unit cell size. The effectiveness of complementary use of both
TEM with electronic diffraction and XRD techniques for structural and substructural parameters determination
while studying magnetite nanosized particles synthesized in polysaccharide matrices is shown in
this paper.
