Abstract

The electric arc furnace slag (EAFS) is a by-product generated during the production of steel in electric arc furnaces. It is a highly versatile material with significant importance in various applications. With its multiple applications and positive environmental impact, EAFS plays a crucial role in sustainable development and resource conservation. The present research focuses on the black slag from SONASID-Jorf steel in Morocco for preparation of Hydroxyapatite (HAP; (Ca5(PO4)3(OH)) phase. This phase was successfully synthesized by activated slag with alkali activator NaOH (Sodium hydroxide) and using a wet precipitation method with molar ratio of Ca/P = 1.67. X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy measurement, scanning electron microscopy (SEM) analysis techniques were performed on the samples to characterize the mineralogical and microstructural properties. The characterization of the developed phases indicates the formation of mixtures of dicalcium silicate with phases of dellaite (Ca6Si3O11(OH)2) and fayalite (Fe2SiO4) in the black slag activated with alkali activator NaOH. Moreover, indicates the formation of the HAP phases synthesized by wet precipitation method. The micrographs obtained by SEM show the morphology of rod-shaped indicate the presence of HAP phase.
