摘要：
A new medical neutral boroaluminosilicate glass with thermal and chemical stabilities conforming to interna-tional standards has been successfully prepared by the traditional melt cooling method. Based on X-ray photo-electron spectroscopy (XPS) and Fourier-transform infrared spectroscopy (FTIR) characterizations, the relationship between the structure and physical and chemical properties of the glass was discussed. The increase of Al2O3 introduction led to the continuous increase of the octahedral proportion of [AlO6], and weakened the degree of glass network connection, which resulted in the increase of thermal expansion coefficient of the glass and the decrease of chemical stability. B3+ ions and Al3+ ions have a competition for free oxygen and basic metal ions, which caused obvious boron-aluminum anomaly. The research has certain guiding significance for the performance standard of medical glass materials and the control of industrial development cost.
