Abstract
The chemical state of particles of 5wt% Fe in α‐Fe2O3 and the subsequently reduced iron particles supported on different particle size (50–200 mesh) of silica (SiO2), alumina (Al2O3), magnesium oxide (MgO) and carbon (C) was examined by Mössbauer spectroscopy at various stages of calcination and reduction. The particle size of the α‐Fe2O3 supported on different mesh sizes (50, 100, 140, 200 mesh) of SiO2 has been determined. The strength of metal‐support interaction with respect to the kind of support was found to be MgO>SiO2>Al2O3>C.Keywords
