  摘要：

  Thermal analysis of some transition metal ferrimaleate precursors, M-3[Fe(mal)(3)](2) . xH(2)O (M = Mn, Co, Ni, Cu) has been studied in static air atmosphere from ambient to 600 degreesC. Various physico- chemical techniques, i.e. TG, DTG, DTA, XRD, IR, Mossbauer spectrometry, have been employed to characterize both the intermediates and final products. After dehydration the anhydrous precursors undergo decomposition to yield an iron(II) intermediate, M[Fe-II(mal)(2)] (M = Mn, Co, Ni, Cu) in the temperature range 160 - 275 degreesC. A subsequent oxidative decomposition of iron(II) species leads to the formation of alpha-Fe2O3 and MO in the successive stages. Finally a solid-state reaction occurs between the oxides above 400 degreesC resulting in the formation of transition metal ferrites, MFe2O4. The ferrites have been obtained at much lower temperature and in less time than in the conventional ceramic method.

  Thermal analysis of magnesium tris(maleato) ferrate(III) dodecahydrate has been studied from ambient to 700 degreesC in static air atmosphere employing TG, DTG, DTA, XRD, Mossbauer and infrared spectroscopic techniques. The precursor decomposes to iron(II) intermediate species along with magnesium maleate at 248 degreesC. The iron(II) species then undergo oxidative decomposition to give alpha -Fe2O3 at 400 degreesC. At higher temperatures magnesium maleate decomposes directly to magnesium oxide, MgO, which undergoes a solid state reaction with alpha -Fe2O3 to yield magnesium ferrite (MgFe2O4) at 600 degreesC, a temperature much lower than for ceramic method. The results have been compared with those of the oxalate precursor.
