Thermal decomposition of FeSO4·H2O in carbon monoxide has been studied at 400–550°C by isothermal experiments. The reaction intermediates and products were identified by X-ray diffraction and Mssbauer spectrometry and determined quantitatively by chemical analyses. In addition to the primary reduction...
摘要: Activation energies for the thermal decomposition reactions of hydrates and basic salts of FeSO 4 were calculated using both conventional and statistical methods. The advantage and disadvantage of both methods is brought out. A combined method is proposed....
Oxidation and thermal decomposition of sodium and potassium borohydrides The thermal decomposition of eleven (II) sulphates has been studied by a combination of thermogravimetric and differential thermal analysis. The relative decomposition temperatures are: MnSO4 755, FeSO4 537, CoSO4 708, NiSO4 675...
2 FeSO4 --> Fe2O3 + SO2 + SO3 (reaction 2) My 1st query : In the second reaction, as iron(II) sulphate undergoes thermal decomposition, why is iron oxidised from Fe2+ to Fe3+? If it was not given in the question that iron(III) oxide was formed, how would the candidate know ...
This shows that the imperfect structure of mullite after clay decomposition is crucial in the successive formation of β-sialon. A carbothermic or alumothermic reaction can also be applied to the synthesis of intermetallic compounds by preliminary mechanochemical treatment of the relevant oxide and the...
Thermal decompositionCu0.5Zn0.5Fe2O4 precursor was synthesized by solid-state reaction at low heat using CuSO45H2O, ZnSO47H2O, FeSO47H2O, and Na2CO310H2O as raw materials. The spinel Cu0.5Zn0.5Fe2O4 was obtained via calcining precursor above 600 C. The precursor and its calcined products ...
TEXTURES OF TETRADECAHEDRON DELTA -FEOOH PARTICLES AND THEIR THERMAL DECOMPOSITION PRODUCTS delta-FeOOH particles have been prepared by oxidation of Fe(OH)2 with H2O2. The Fe(OH)2 precursors precipitated from a concentrated FeSO4 solution were aged at different temperatures from 40 to 110-degrees-...
were under co-pyrolysis in the argon atmosphere. The characterization of ZIF-8 was exhibited in Supplementary Figs.2-4. During co-pyrolysis around 340 °C, the H2O vapor by decomposition of hydroxyl groups from filter papers in situ released, confirmed by thermogravimetric analysis coupled with...
FeSO4·6H2Omass spectrometryThe thermal decomposition of FeSO4•6H2O was studied by mass spectroscopy coupled with DTA/TG thermal analysis under inert atmosphere. On the ground of TG measurements, the mechanism of decomposition of FeSO4•6H2O is: i) three dehydration steps FeSO4•6H2O FeSO4...
