Abstract

The synthesis of zinc ferrite powders is carried out by combustion of a mixture of iron, iron oxides and zinc oxide powders in oxygen. An increase of oxygen pressure increases both the combustion temperature and velocity. The combustion reaction can not be self-sustained when the oxygen pressure is below 0.3MPa. The results of XRD and Mössbauer spectroscopy show that intermediate phases of iron oxide, Fe_1-xO, Fe_1-zO and crystal defects appear when the oxygen pressure is excessively low or high. An analysis of the dependence of the degree of conversion to ferrite on the oxygen pressure has been made. In addition, the reaction mechanism associated with the combustion synthesis (CS) of ZnFe₂O₄ is proposed.
