  • 摘要:In the present work we have shown a novel Barium hexaferrite (BaFe12O19 - BaF) powder synthesized by a sol-gel combustion route using metal nitrates and D-Fructose. BaFe12O19 precursor was calcined using microwave furnace at 900°C for 10 minutes. The products were characterized by X-ray diffraction (XRD), high resolution scanning electron microscope (HR-SEM), and vibrating sample magnetometer (VSM), whose results indicate that they have well crystalline phase of barium hexaferrite, the diameter of the hexagonal platelet-like structure ranges from 50 to 100 nm. Magnetic measurements showed that the coercivity was 5558.6 Oe and saturation magnetization was 55.20 emu/g. Magnetic measurements for the barium hexaferrite showed enhanced coercivity.Keywords: Sol-gel combustion; Hexaferrite; D-Fructose; Remanent magnetization; Precursor.© 2011 JSR Publications.
