Preparation of Magnetite-Mg/Al Hydrotalcite through Hydrothermal Process and Subsequent Calcination

Abstract:

Fe₃O₄/Mg-Al-NO₃-hydrotalcite composite compounds have been synthesized by hydrothermal process followed by calcination to learn the differences in physical and chemical properties of each compound. Hydrothermal was performed at a temperature of 120 °C for 5 h and calcinations was at 450 °C for 3 hours. Characterization of the composite compounds was conducted using the Fourier Transform Infrared Spectroscopy (FTIR), the X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) and Vibrating Sample Magnetometer (VSM). The characterization results showed that crystallinity, surface area and magnetic properties of hydrothermally treated Mg/Al hydrotalcite-magnetite were higher than those unhydrothermal and calcination products.
