摘要: 以Na2O-B2O3-SiO2低膨胀玻璃为基础玻璃体系,用B2O3逐步取代SiO2,采用高温熔融法制备出低膨胀硼硅酸盐玻璃。通过红外光谱、扫描电镜分析了玻璃微观结构,X射线光电子能谱分析了桥氧和非桥氧含量,研究了B2O3含量对硼硅酸盐玻璃机械性能、热膨胀性能和紫外-可见光透过率的影响。结果表明:B2O3含量的增加使玻璃结构中的[BO3]增多,玻璃分相逐渐加重;该体系玻璃的机械性能良好,显微硬度达802 kg/mm2,抗折强度达147 MPa;转变温度和软化温度都逐渐降低,热膨胀系数逐渐增加;玻璃样品的可见光透过率在90%左右,无明显规律,[BO3]增多,玻璃结构中非桥氧的含量增加,玻璃的紫外-可见光透过率逐渐降低。

Abstract: The low expansion borosilicate glass was prepared by using Na2O-B2O3-SiO2 low expansion glass system and gradually replacing SiO2 with B2O3 by high temperature melting method. The microstructure of borosilicate glass was analyzed by infrared spectrum and scanning electron microscopy. The content of bridged oxygen and non-bridged oxygen was analyzed by X-ray photoelectron spectroscopy. The effects of the content of B2O3 on the mechanical properties, thermal expansion properties and UV-Vis transmittance of borosilicate glass were studied. The results show that [BO3] in glass structure increases with the increase of B2O3 content, and the phase separation of glass becomes more and more serious. The glass system has good mechanical properties, with microhardness up to 802 kg/mm2 and flexural strength up to 147 MPa. The transition temperature and softening temperature decreased gradually, and the thermal expansion coefficient increased gradually. The visible light transmittance of the glass sample is about 90% without an obvious rule. The increase of [BO3] increases the content of non-bridged oxygen in the glass structure, and the UV-vis transmittance of the glass decreases gradually.

Key words: B2O3, UV-Vis transmittance, low expansion glass, thermal expansion property, mechanical property
