Description

Iron carbide nanoparticles were produced by ultrasonication of ferrocene in diphenylmethane and their properties were investigated using Moessbauer spectroscopy, Transmission electron microscopy and X-ray diffraction. The as-prepared particles were amorphous paramagnetic iron carbides, and the particles obtained after annealing exhibited magnetic components. The particles obtained after annealing at 873 K under argon flow for 2 h consisted of Fe3C, α-Fe, and paramagnetic iron carbide, while Moessbauer spectra indicated that no iron oxides were present.
