Abstract

In the present study, zinc-substituted magnetites of the Fe3 − X Zn X O4 type were prepared by co-precipitation in the range 0 ≤ X ≤ 1 and, further, annealed in free atmosphere, at 800° for 3 h. The samples were characterized by X-ray diffraction and Mössbauer spectroscopy. The results showed that the annealed samples were oxidized and converted into Fe2O3 and ZnFe2O4, in relative amounts that varied with X.
