Abstract Scope |
A solid-solid reaction took place at 1000°C during 4 h, using a mixture of pure iron oxide- Fe2O3 and pure zinc oxide – ZnO in order to synthesize zinc ferrite-ZF of different compositions: (S1) Fe2O3/ZnO:3/2, (S2) Fe2O3/ZnO:1/1, (S3) Fe2O3/ZnO:4/1 and (S4) Fe2O3/ZnO:2/1. Each of these mixtures were milling during 24 h before the thermic treatment carried out. S1, S2, S3 and S4 samples were became to M1, M2, M3 and M4 samples respectively, which after that were thermally characterized using DSC, DTA and TG techniques. In sequence the ZF produced were examined using XRD, optical and magnetic techniques, SEM & TEM. Previous studies of magnetic characterization observed a little hysteresis of this equimolar ZF. The results of estimation of the band gap energy (Eg) via the manipulation of the Kubelka-Munk theory allowed to determine that the samples M1, M2, M3 and M4 are considered semiconductors (3.66 and 3.76 eV). |
