Abstract :
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.
