Description In this study, amorphous iron-boron alloy nanoparticles successfully synthesized by mechanochemical
method. The raw materials were ferrous sulfate heptahydrate (FeSO4.7H2O) as a source of iron and sodium
borohydride (NaBH4) as a reducing agent. Powders grinding was performed with different
NaBH4/FeSO4.7H2O molar ratio. The results revealed that high active and completely amorphous particles
could be synthesized with the molar ratio of 4:1 for NaBH4:FeSO4 in 10 minutes of grinding time. Various
characterizations, such as the chemical analysis, atomic absorption spectroscopy (AAS), fourier transform
infrared spectroscopy (FT-IR), x-ray diffraction (XRD) and field emission scanning electron microscopy
(FESEM) have been performed. The XRD results confirmed the formation of the amorphous phase. Other
results also indicate the formation of amorphous alloy nanoparticles with an average particle size below 50
nm and the composition was Fe-10 Wt
percent B.
