The prepared nanoparticles were heated at 1000 oC to study their physicochemical properties. The XRD results pointed out the multiphase for the samples. The morphological results revealed that the uniformity increased by increasing iron atoms rate. TEM analysis revealed that the particle with a size of 40 nm was obtained for 4% of the sample. The results of FT-IR analysis indicated that when the 2% impurity increases the AlO4 tetrahedra and AlO6 octahedral vibrational bond grow. %U https://ijcce.ac.ir/article_38036_a3fae4cea6adf9140deeb728a7b0533e.pdf
