Abstract
The influence of mechanical milling and subsequent calcination of a 1:1 molar mixture of CuO and α-Fe2O3 on the formation of CuFe2O4 has been investigated with X-ray powder diffraction (XRD) and Mössbauer spectroscopy. Pre-milling the mixture for 160h leads to the formation of CuFe2O4 nanocrystallites at 750°C. This temperature is ca. 400-450°C lower than the temperatures at which the material is conventionally prepared using the ceramic technique that involves no pre-milling of the reactants. Rietveld refinement of the XRD reveals the presence of both cubic and tetragonal crystal structures in the CuFe 2O4 obtained.
