Abstract
The chemical states of tin in converted tin phosphate coatings on iron and steel and in tin phosphate powders were analysed by conversion electron Mössbauer spectrometry and transmission Mössbauer spectrometry. The tin species in stannous phosphate, stannic oxide and metallic tin were recognized in the converted tin phosphate coatings. Mössbauer parameters of Sn(II) included in the phosphate coatings were slightly different from those of Sn(II) incorporated in powders of zinc and manganese phosphate compounds. The tin atoms mainly occupied two different sites in three sites of stannous phosphate structure, depending on the preparations.
