Abstract
Mössbauer spectroscopy was used to study corroded iron after treatment with phosphoric acid or commercial rust transformers. It was found that treatment produced normal iron phosphates from metallic iron, hematite and FeO, and acid ferric phosphate FeH<sub>3</sub>(POI4I)I2I. 2.5H<sub>2</sub>O from alphaand gamma Fe<sub>2</sub>O<sub>3</sub> and alpha, beta, and gammaFeOOH. When these last are present, phosph oric acid treatment does not produce a protective, inhibiting layer. See also AATA 19-702. -- AATA
