The influence of the aging in a highly alkaline medium at 160 °C on the microstructural properties of α-FeOOH was monitored by XRD, 57Fe Mössbauer and FT-IR spectroscopies and FE-SEM. In the synthesis of acicular and monodisperse α-FeOOH particles, tetramethylammonium hydroxide was used as a precipi...
