在化学组成为40Na2O·60P2O5的基础上,用CaO、MgO取代Na2O或用Al2O3、B2O3和SiO2取代P2O5制备5种磷酸盐玻璃体系,用X射线衍射(XRD)和傅立叶变换红外光谱(FTIR)对玻璃结构进行了表征,并测定了该玻璃体系样品的密度、化学稳定性等基本性质。研究发现,用CaO取代Na2O和Al2O3取代P2O5可以显著改善玻璃的化学稳定性;用SiO2取代P2O5时,玻璃的化学稳定性下降;由于配位问题,B2O3和MgO对磷酸盐玻璃结构与性能的影响出现转折点。

Based on the chemical composition of 40Na2O·60P2O5,Na2O was replaced by CaO or MgO while P2O5 was replaced by Al2O3, B2O3 or SiO2 respectively. Five kinds of phosphate glass system was prepared,which were characterized using X-ray diffraction( XRD) and Fourier transform infrared spectroscopy( FTIR) . The density, chemical durability of the glass system, as the basic nature, were determined. It was found that the introduction of CaO and Al2O3 can significantly improve the glass chemical stability,while SiO2 destroyed the network structure of phosphate glass. Due to coordination problems, there is a turning point for the influence of B2O3 or MgO on the structure and performance of phosphate glass.
