Preparation and Characterization of Coprecipitation-derived Ferromagnetic Glass-ceramic for Hyperthermia Application

摘要

Ferromagnetic glass-ceramics could be used for magnetic induction hyperthermia. A ferromagnetic glass-ceramic in the system SiO_2-Na_2O-CaO-P_2O_5-Fe_2O_3 has been prepared by melting of the coprecipitation-derived precursor. Using the coprecipitation-derived method, the molecular-scale homogenously glass precursor was obtained. This glass-ceramic contains a unique magnetite crystals precipitate during cooling from melting temperature without any nucleation and crystallization treatment. The crystallization of the glass systems with different component has been systematically investigated by using XRD, as well as vibrating sample magnetometer (VSM).
