Abstract
A series of Al2O3-Fe2O3 mixed oxidic solids with composition ranging from 0 to 100% of Fe2O3 were prepared and examined for structural characteristics . XRD diagrams showed the presence of alpha -Al2O3 and hematite phases. The analysis of Mossbauer spectra revealed the existence of two iron containin g phases. The specific surface area of the mixture decreases by the additio n of iron and depends on the crystal phases of the mixture.
