In Situ and Ex Situ X-ray Diffraction and Small-Angle X-ray Scattering Investigations of the Sol-Gel Synthesis of Fe₃N and Fe₃C.

ABSTRACT: Iron nitride (Fe₃N) and iron carbide (Fe₃C) nanoparticles can be prepared via sol-gel synthesis. While sol-gel methods are simple, it can be difficult to control the crystalline composition, i.e., to achieve a Rietveld-pure product. In a previous in situ synchrotron study of the sol-gel synthesis of Fe₃N/Fe₃C, we showed that the reaction proceeds as follows: Fe₃O₄ → FeO_x → Fe₃N → Fe₃C. There was considerable overlap between the different phases, but we were unable to ascertain whether this was due to the experimental setup (side-on heating of a quartz capillary which could lead to thermal gradients) or whether individual particle reactions proceed at different rates.
