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.
