The present paper deals of the ZF synthesis using a ceramic method focusing its formation from an equimolar mixture of pure iron oxide-Fe2O3, and zinc oxide-ZnO. The solid-solid reaction took place by thermic treatment, between 650 to 1200°C. The DTA showed an endothermic pick at 760.58°C and an exothermic pick at 1115.45°C. By TGA was determined a loss of mass of ZF of 0,009% approximately. SEM showed particles of ZF predominantly of spherical geometry and in particular, the TEM scans, reveled type micrometric and homogeneous agglomerates formed from single crystal round particles having size of circa 100 nm. XRD characterization shows up three different spinelics phases of ZF: Fe 1.78O3.71 Zn 0.945; Fe1.92O4Zn1.08 and Fe2O4Zn. Previous studies of magnetic characterization of ZF observed a little hysteresis due those three spinelics phases achieved a 90.2% which means this sample has a minimum presence of iron oxides in a form of magnetite.
