Preparation and Characterization of Zinc Oxide Doped with Ferrite and Chromium
MetadataShow full item record
In this paper, the effect of doping concentrations of Fe and Cr on ZnO powder was studied by using X-ray diffraction (XRD). The ZnO was doped using solid state reaction method with High Speedshaker Mill (HSM) and continued with sintering at 900 C for 4 hours. Samples doped with Fe and Cr have polycrystalline hexagonal wurtzite structure. XRD pattern of ZnO doped with Fe is not far different from that with Cr. The intensity decrease and the peak shifted to a higher 20 angle indicate the change in the crystal parameters such as lattice parameters, crystalline sizes, and d-spacing.
