Synthesis and characterization of nanocrystalline BaFe12O19 obtained by using glucose as a fuel

Nanocrystalline BaFe12O19 powders are successfully synthesized by using glucose as a fuel. The effects of the calcination temperature on the morphology, crystalline structure and magnetic properties of the barium ferrite particles are characterized by thermal gravimetric/differential thermal analyzer, field emission scanning electron microscope, X-ray diffractometer and vibrating sample magnetometer. Pure barium ferrite powders with a crystal particle size of 60 nm are obtained at temperature as low as 900 °C, showing a saturation magnetization (Ms) of 53 emu/g, a coercivity (Hc) of 5.3 kOe and a squareness of 0.573.
