Description
Summary:In this paper, the effect of the structural properties and morphology of iron oxide product, have been studied in co-precipitation and hydrothermal methods. Also, the effect of adding CCl4 impurities and final annealing of the materials is taken into account. The more homogeneous particle size in hydrothermal method has been explained by the effect of adding CCl4 as impurities to prevent the continuation of nucleation. It has also been observed that in co-precipitation sample additive has a key role for providing the bar shape particles by mediating of the anisotropic connection of nuclei. The difference in the crystal structure of the anneal samples has been related to the oxygen content.
