SYNTHESIS AND CHARACTERIZATION OF MAGNETITE NANOPARTICLES

Abstract

Magnetite (Fe₃O₄) nanoparticles have garnered the attention of researchers in the fields of renewable energy, electronics, and medicine over the past decade due to their magnetic and high magnetic susceptibility. The unique properties of magnetite make it an essential material for the development and advancement of renewable technologies. To obtain magnetite powder through hydrothermal synthesis, the precursors used were FeCl₂·4H₂O and FeCl₃·6H₂O aqueous solutions with a molar ratio of 1:2, and NaOH solution with a concentration of 2 M was used as the hydrolysis agent. The reaction took place at varying temperatures of 85°C, 150°C, and 200°C, and a pressure of 20 bar. The resulting powders were then subjected to morpho-structural characterization using techniques such as scanning electron microscopy and X-ray diffraction
