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. |
