Краткое описание

Nano-Fe3O4 particles have been prepared by a chemical reduction method using ferric chloride hexahydrate as a starting compound and hydrazine hydrate as a reducing agent in the presence of polyethylene glycol matrix (PEG-200). The prepared nano-Fe3O4 was characterized by NANOPHOX particle size analyzer, powder X-ray diffractometer (XRD), atomic absorption spectroscopy (AAS), and high-resolution transmission electron microscopy (HR-TEM). The particle size of nano-Fe3O4 was in the range of 38−69 nm. The powder XRD pattern reveals that the crystallite size of nano-Fe3O4 is around 15−17 nm and the purity is better than 99.5%. HR-TEM supports the particle size measurements and shows that the particles are almost spherical in shape. The effect of nano-Fe3O4 on ammonium perchlorate was also studied and results indicate that it reduces its thermal decomposition temperature. Also, the prepared nano-Fe3O4 was evaluated in composite propellant formulations at different ratios and findings reveal that acceleration in burning rate was approximately 15% greater in comparison to the nano-Fe2O3-based composition.
