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 containing phases. The specific surface area of the mixture decreases by the addition of iron and depends on the crystal phases of the mixture.
