The Influence of Cr-dopant on the properties of alpha-FeOOH particles precipitated in highly alkaline media

The effects of Cr-dopant on the phenomenology of the precipitation of acicular alpha-FeOOH particles, the formation of solid solutions, particle size and shape were investigated using X-ray powder diffraction (XRD), Mossbauer and FT-IR spectroscopies and field emission scanning electron microscopy (FE-SEM). Acicular and monodisperse alpha-FeOOH particles were precipitated at a very high pH by heating the suspension obtained by adding a tetramethylammonium hydroxide solution to the aqueous solution of FeCl3
