Preparation and Characterization of SrO-Fe₂O₃-FeO-SiO₂-B₂O₃ System Hexaferrites Glass-Ceramics

Abstract:

Based on the SrO-Fe2O3-FeO-SiO2-B2O3 system, the M-type strontium hexaferrites glass ceramics has been prepared through heat treating the melted glass. Using the aqueous solution solvent evaporation and melt method, we obtained the glass precursor of molecular-scale homogenously mixed compound. The precursor was completely melted in a lidded platinum crucible placed in an electric furnace at 1480°C for 1h and then annealed in a furnace at 550°C for 40min. The crystallization of the glass systems with different component has been systematically investigated by using X-ray diffraction (XRD), Transmission Electron Micrographs (TEM) as well as Vibrating Sample Magnetometer (VSM). It is found that Fe3O4 crystal precipitated during naturally cooling the melt from 1480°C to anneal temperature. Moreover, the hexaferrite glass ceramics with the main crystal phase of SrFe12O19 was obtained after heat-treated at 860°C for 2 hours. The magnetic properties of the obtained hexaferrite glass ceramics indicated that the saturation magnetization and the coercivity were 8.1A•m2/kg and 114KA/m, respectively.
