Preparation of Fe₃O₄-Coated Microsilica Composites via Chemical Reduction Method

Abstract:

Fe₃O₄-coated microsilica composites were synthesized by a novel method. The struction like precursor Fe₃O₄ nanoparticles as the shell and microsillica as the core for the composite has been prepared by chemical reduction method. The Fe₃O₄-coated microsilica composite presents a saturation magnetization value of 38.03 emu/g, which is sufficient to complete magnetic separation. The synthesized magnetic composites are characterized by X-ray diffractometer (XRD), transmission electron microscope (TEM) and vibrating sample magnetometer (VSM). The results indicated that Fe₃O₄ nanoparticles successfully coated on microsilica.
