Abstract
Research was performed on both phosphoric and tannic acids as chemical s for rust transformation. The interaction and phase transformation ki netics of the reaction between these products when mixed with differen t iron oxides and oxyhydroxides were studied. Infrared spectroscopy (I R) results of all formulations indicated that lepidocrocite (gamma-FeO OH) was the most reactive to acids followed by goethite (alpha-FeOOH) and magnetite (Fe3O4). No lepidocrocite to magnetite transformation in duced by tannic acid. (C) 1997 Elsevier Science Ltd.
