Preparation and Characterization of SrO-Na2O-Fe2O3-FeO-P2O5-SiO2 Ferrimagnetic Glass-Ceramics for Hyperthermia Application

The ferrimagnetic glass-ceramic based on SrO-Na2O-Fe2O3-FeO-P2O5-SiO2 system was prepared for hyperthermia application using aqueous aolution-melt method. Using the aqueous solution solvent evaporation, we obtained the molecular-scale homogenously glass precursor. 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 annealed glasses were heat treated at 1050°C for 1h to obtain the glass-ceramics. The crystallization of the glass systems with different component has been systematically investigated by using XRD, TEM, as well as vibrating sample magnetometer (VSM). The glass-ceramics with P2O5=5.0wt% show a strong magnetic, which contains highest value of specific saturation magnetization of 24.89A•m2/kg.

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.

A glass-ceramic belonging to the CaO-Al2O3-SiO2(CAS) system with different composition of spodumene and doping the Li2O with amount between 0~2.5 % (mass fraction) were prepared by onestage heat treatment, under sintering and crystallization temperature at 1120 °C for two hours. In this paper, differential thermal analysis, X-ray diffraction, scanning electron microscopy, energy dispersive spectrometry and bending strength test were employed to investigate the microstructure and properties of all samples. β-wollastonite crystals were identified as the major crystalline phases, and increasing Li2O was found to be benefit for the crystallization and tiny crystalline phases remelting, resulting in the content of major crystalline phases increased first and then decreased with increasing the expense of spodumene. Meanwhile, the crystal size can be positively related with the content of Li2O. The preferable admixed dosage of spodumene can be obtained, besides the strength of glass-ceramics can be more than 90 MPa.

Microstructure Observation

In present work, two conductive filler (carbon fiber with Nickel (Ni) coatings and carbon fiber with Nickel/Fe3O4 nanoparticle (Ni/Fe3O4-NPs) composite coatings) were prepared by electrodeposition. Microstructure observation indicated that the coatings were deposited uniformly on the surface of fiber. Vibrating sample magnetometer (VSM) and electromagnetic interference (EMI) shielding test showed that the two conductive filler has good saturation magnetization and EMI shielding effectiveness.The conductive filler of carbon fiber with Ni/Fe3O4-NPs composite coatings was more excellent. They are promising for application in electromagnetic shielding materials.
