Ni0.5Mn0.1Zn0.4Fe2(C4H204)3.6N2H4 PRECURSOR AND Ni0.5Mn0.1Zn0.4Fe204NANOPARTICLE Preparation, IR spectral, XRD, SEM-EDS and thermal analysis

摘要

Metal carboxylato-hydrazinates are very good precursors for the synthesis of metal as well as mixed metal oxides as these, mostof the times decomposes to nanosized oxides with high surface area at comparatively lower temperatures. In the present study onesuch novel precursor has been prepared and characterized by XRD, IR, SEM-EDS and chemical analysis. The thermal decompo-sition of the precursor has also been studied by isothermal, differential scanning calorimetry (DSC) and thermogravimetric analy-sis (TG). The precursor shows two-step dehydrazination followed by decarboxylation to form Ni0.5Mn0.1Zn0.4Fe204. The infraredspectra show N-N stretching frequency at 972 cm-1which confirms the bidentate bridging hydrazine. XRD confirms the forma-tion of single phase Ni0.5Mn0.1Zn0.4Fe204.
