Quantitative X-ray structural analysis using an in-house X-ray diffraction apparatus and transmission electron microscopy have been used for characterizing the structure and morphology of γ-FeOOH (Lepidocrocite) particles, which were prepared by immersing a pure iron, an iron-3 mass% aluminum alloy and an iron-0.58 mass% phosphorus alloy into aqueous solutions containing sodium chloride. The atomic-scale structure in the γ-FeOOH particles was estimated by fitting the interference function with the help of the reverse Monte Carlo (RMC) simulation technique. The results indicated that the structure of the particles is deviated from ideal γ-FeOOH structure, as the linkages of FeO_6 octahedral units were distorted in the particles. The structural distortion is considered to be due to the influence of aluminum and phosphorus on the formation of γ-FeOOH particles.報文Original Paper
