摘要：为了探索稀土氧化物Y2O3掺杂对硅酸盐玻璃结构及其高温熔体黏度的影响，用熔融–水淬法制得了掺杂不同含量Y2O3的Na2O–CaO–SiO2系玻璃料，采用激光共聚焦Raman光谱仪和高温旋转黏度计分别对玻璃料进行了Raman光谱和黏度的测试，根据Arrhenius方程推算了玻璃的熔制温度，同时给出了计算玻璃结构中每个四面体中的氧数、非桥氧数、平均桥数及非桥氧比例的公式。结果表明：Y2O3的掺杂使得Na2O–CaO–SiO2系玻璃中，具有不同非桥氧的结构单元之间发生了一定转化。随着Y2O3掺杂量的增加，玻璃中每个四面体中的氧数和非桥氧数都逐渐增大，玻璃中每个四面体中的连接数降低。此外Y2O3的掺杂降低了Na2O–CaO–SiO2系玻璃的高温黏度与熔制温度，且与玻璃结构的变化规律相一致。

Abstract: Silicate glasses and melts, soda lime silicate glass frits with various contents of Y2O3 were prepared via melting-quenching in water. The effect of Y2O3 on the structure and viscosity was investigated. The samples were characterized by Raman spectrometer and viscometer, respectively. The melting temperature was obtained based on the Arrhenius equation. Some expressions for the glass structure (i.e., fraction of non-bridging oxygen, average number of non-bridging oxygen per tetrahedron, average number of oxygen pre tetrahedron and average number of bridging corners per tetrahedron) were proposed. The results show that Y2O3 doped into soda lime silicate glass can change the [SiO4] tetrahedron structural unit, and the average number of non-bridging oxygen per tetrahedron and the average number of oxygen pre tetrahedron both increase and the average number of bridging corners per tetrahedron decreases with increasing the content of Y2O3. In addition, the incorporation of Y2O3 also decreases the viscosity and melting temperature of soda lime silicate glass.
