Preparation and Characterization of Fe2O3-SiO2-Y2O3-Al2O3 Ferromagnetic Glass Ceramics Microspheres for Hyperthermia Application
摘要
Abstract
Novel ferromagnetic glass ceramic microspheres (FGCMs) containing yttrium which can be used for clinical applications combining features of radiotherapy and hyperthermia were prepared by heat treatment and flame spray method. Influence of the heat treatment of ferromagnetic glass ceramic was investigated by the differential thermal analysis (DTA) and X-ray diffraction (XRD).Morphology of the FGCMs was characterized by the polarizing microscopy. Magnetism property and heating power of the FGCMs were measured by a vibrating sample magnetometry(VSM) and a thermomagnetic measurement equipment, respectively. Amount of crystallized magnetite was calculated by the XRD and VSM data. Specific heat values and specific absorption rate values of the FGCMs was calculated to characterize the heating ability of the FGCMs. The experimental results show that the FGCMs have great potential to offer the dual-function of hyperthermia and radiotherapy in the treatment of cancer.关键词
