| 摘 要： | 采用溶胶-凝胶法制备CaO-P2O5-SiO2-Na2O-B2O3体系前驱体粉末,用CaF2替代部分CaO再次制备前驱体粉末。 通过TG-DSC分析确定结晶温度为865 ℃,经过热处理获得主晶相为Na6Ca3Si6O18的玻璃陶瓷。 通过X射线衍射(XRD)、傅里叶红外光谱(FTIR)、扫描电子显微镜(SEM)等技术手段及体外生物活性实验分析玻璃陶瓷的显微结构及性能。 结果表明,CaF2的加入能提高玻璃陶瓷的体积密度、抗折强度和弹性模量,并且不会破坏玻璃陶瓷的生物活性。

| Abstract: | By partially substituting of CaO with CaF2, in CaO-P2O5-SiO2-Na2O-B2O3 glass-ceramic system a new precursor powder was prepared by the sol-gel method. Its crystallization temperature was determined by TG-DSC at 865 ℃. The main crystal phase of the glass-ceramics is Na6Ca3Si6O18. The microstructures and properties of this glass-ceramics were characterized by X-ray diffractometry (XRD), Fourier transform infrared spectroscopy(FTIR), scanning electron microscopy(SEM) and in vitro assays. By addition of CaF2, the volume density, bending strength and microhardness of the glass-ceramics are significantly improved, but the bioiogical activity of the glass-ceramics is maintained. |
