The broadening of selected X‐ray diffraction peaks in goethite‐derived Fe 2 O 3 was studied in terms of the structure factors of the oxygen and iron atoms. Calculation of the structure factors in the ideal corundum and Fe 2 O 3 lattices showed that the intensities of the broad peaks result primarily from the iron atoms. Thus, preferential line broadening in goethite‐derived Fe 2 O 3 is interpreted in terms of incomplete displacement of iron atoms during decomposition.
