epsilon-Fe2O3 nanoparticles synthesized in atmospheric-pressure microwave torch

Materials Letters 116 (2014) 370-373

The article reports on epsilon-Fe2O3 nanoparticles synthesized in a single step by atmospheric-pressure microwave torch discharge using gaseous precursors only. Morphology and composition of the as-synthesized nanopowder were studied by HR-TEM, XRD, and Mossbauer spectroscopy. In the studied nanopowder, epsilon-Fe2O3 phase (d(xRD)=25 nm, 32 wt%) together with alpha-Fe2O3 and gamma-Fe2O3 phases was found. The characteristic epsilon-Fe2O3 and alpha/gamma-Fe2O3 sextets in the Mossbauer spectra measured at 293 and 5 K confirmed the phase composition of the powder. Compared with the methods currently used for the synthesis of epsilon-Fe2O3 nanoparticles, atmospheric-pressure microwave torch discharge appears as a new synthesis route for obtaining epsilon-Fe2O3 nanoparticles.
