摘要：

In this study, the synthesis and characterization of the akaganeite, phase beta-FeO(OH), was performed. Scanning electronic microscopy images revealed that the crystals formed in the first 4 h of hydrolysis had the same morphology as those of crystals formed at the end. X-ray diffractometry and vibrational spectra showed that the principal phase obtained from the hydrolysis of iron chloride at 90 degrees C was akaganeite. Rietvield refinement revealed that hematite formed along with the akaganeite at this temperature, in the proportion of 10% and 90%, respectively. Simultaneous thermal analysis showed the characteristic profile of only the akaganeite. (c) 2013 Published by Elsevier B.V.
