Abstrak

In the present study, XRD, SEM/EDS, Raman, EMR/EPR spectroscopy, and vibrating sample magnetometry (VSM) were used to analyze the reduction of hematite by the carbonization products of waste activated sludge (WAS) at 500–1000 °C. The reduction process includes the following steps: α-Fe<sub>2</sub>O<sub>3</sub> → Fe<sub>2</sub>O<sub>3</sub> + Fe<sub>3</sub>O<sub>4</sub> (T<sub>tr</sub>~500 °C) → Fe<sub>3</sub>O<sub>4</sub> (T<sub>tr</sub>~600–700 °C) → FeO → Fe<sub>amorph</sub>. (T<sub>tr</sub>~1000 °C). The prevalence of certain phase compositions at different hematite reduction temperatures makes it possible to predict the areas viable for the application of reduced oxides: adsorbents (after T<sub>tr</sub>~500 °C) → soft ferromagnetic materials (after T<sub>tr</sub>~600–700 °C) → electrically engineered amorphous iron (after T<sub>tr</sub>~1000 °C).
