Abstract
Two iron(III) oxide hydroxides, namely alpha-FeOOH (goethite) and gamm a-FeOOH (lepidocrocite), were studied by means of Differential Thermal Analysis (DTA), Thermogravimetry (TG) and Emanation Thermal Analysis (ETA) on heating in air. Surface area, Transmission Electron Microscop y (TEM) and X-ray diffraction patterns (XRD) were used for the charact erization of the intermediate products of the thermal treatment. ETA e nabled us to obtain a new sensitive insight into the aggregation proce sses of solid particles.
