Abstract

The oldest rust from the Delhi iron pillar was characterized by Fourier transform infrared spectroscopy (FTIR). The constituents of the scale were -, -, -FeOOH, Fe3-xO4 and phosphate. The FTIR results also revealed that the scale was hydrated. The unambiguous identification of the iron oxides/oxyhydroxides in the FTIR spectrum implies that they are present in the amorphous state as x-ray diffraction (XRD) analysis did not reveal these phases. The results of the present study are compared with earlier FTIR spectroscopic results of atmospheric rust formation.
