Description

The dataset represents the TG-DSC curves of the mixtures containing ferrites (MFe2O4, where M = Zn, Cu or Zn0.5Cu0.5) and iron sulfates (Fe2(SO4)3∙9H2O or FeSO4∙7H2O). The data was collected for pure iron sulfates, as well as for 6 ferrite-sulfate mixtures, namely, Fe2(SO4)3∙9H2O + Zn0.5Cu0.5Fe2O4, Fe2(SO4)3∙9H2O + CuFe2O4, Fe2(SO4)3∙9H2O + ZnFe2O4, FeSO4∙7H2O + Zn0.5Cu0.5Fe2O4, FeSO4∙7H2O + CuFe2O4, FeSO4∙7H2O + ZnFe2O4. Temperature ranges of all peaks obtained during the heating of the mixtures approximately match with the temperature ranges of peaks of thermal decomposition of pure sulfates that indicates the identity of the interaction mechanism in all the studied ferrite-sulfate systems.

Steps to reproduce

TG-DSC analysis was carried out using SDT Q-600 (TA Instruments, New Castle, DE, USA) device. The mixtures of 15-40 mg in weight were heated with a rate of 10 °C/min within the temperature range of 25–900 °C in corundum crucibles in air. Analytical grade reagent Fe2(SO4)3∙9H2O and grade reagent FeSO4∙7H2O were used. The data was collected for pure iron sulfates, as well as for 6 ferrite-sulfate mixtures, namely, Fe2(SO4)3∙9H2O + Zn0.5Cu0.5Fe2O4, Fe2(SO4)3∙9H2O + CuFe2O4, Fe2(SO4)3∙9H2O + ZnFe2O4, FeSO4∙7H2O + Zn0.5Cu0.5Fe2O4, FeSO4∙7H2O + CuFe2O4, FeSO4∙7H2O + ZnFe2O4. The compositions of the mixtures are based on the molar ratios Fe2(SO4)3 : MFe2O4 = 2 : 1 and FeSO4 : MFe2O4 = 4 : 1.
