Abstract

Nowadays there is a high interest in the recovery of industrial steel waste into useful by-products. For that purpose, it is important to know the physical and chemical properties of steel slag in order to better understand its characteristics and thus seek applications. In this work, we study primary steel slag formed in an electric arc furnace (EAF). Here we present the structural characterization and magnetic properties of the slag performed by X-ray fluorescence spectroscopy (XRF), X-ray diffractometry (XRD), scanning electron microscopy (SEM), magnetic measurements and Mössbauer spectroscopy. The elements Zn, Fe, Cl, Ca, and K and the phases Fe₃O₄, Zn₅(OH)₈Cl₂.H₂O, ZnO, and KCl were identified by XRF and XRD, respectively. Mössbauer spectroscopy at room temperature shows one doublet typical for Fe²⁺, and sextets corresponding to Fe₃O_4, and Fe₂O₃. ⁵⁷Fe-Mössbauer spectroscopy appears as a necessary tool in metallurgical slag research.
