Abstract:
Metal carboxylato-hydrazinates are very good precursors for the synthesis of metal as well as mixed metal oxides as these, most of the times decomposes to nanosized oxides with high surface area at comparatively lower temperatures. In the present study one such novel precursor has been prepared and characterized by XRD, IR, SEM-EDS and chemical analysis. The thermal decomposition of the precursor has also been studied by isothermal, differential scanning calorimetry (DSC) and thermogravimetric analysis (TG).The precursor shows two-step dehydrazination followed by decarboxylation to form Ni0.5Mn0.1Zn0.4Fe2O4. The infrared spectra show N-N stretching frequency at 972 cm(-1) which confirms the bidentate bridging hydrazine. XRD confirms the formation of single phase Ni0.5Mn0.1Zn0.4Fe2O4.
