Preparation of Co0.5Zn0.5Fe2O4 and Co0.5Mn0.5Fe2O4 Nanoferrites by Co-Precipitation Method
Abstract:
Nanoparticles of Cobalt-zinc ferrite (Co0.5Zn0.5Fe2O4) and Cobalt-manganese ferrite (Co0.5Mn0.5Fe2O4) have been synthesized at room temperature by co-precipitation method with and without calcination process. Starting materials for preparation of nanooxides were Co (NO3)2.6H2O, ZnCl2, Fe (NO3)3.9H2O and Mn (NO3)2.4H2O. These salats were mixed in stoichiometric amounts and precipitated with sodium hydroxide. Synthesised materials are confirmed by XRD and SEM analysis. The FTIR spectra of nanooxides have been analyzed in the frequency range of 400-4000cm-1.
