| 摘 要： | 封接玻璃具有耐热好、化学稳定性和机械强度高的优点,被大量运用在真空微电子技术及航天和汽车等众多行业领域。磷酸盐玻璃具有低成本、低特征温度、低稳定性等特点,常被用于封接玻璃的制备。本文采用高温熔融法制备了(60-x)SnF2-xSnO-35P2O5-5WO3(x=0%,5%,10%,15%,20%,质量分数)组成的玻璃,研究了SnO含量对玻璃结构和性能的影响。通过红外光谱表征了玻璃的微观结构,并测定了玻璃的热膨胀系数和特征温度数值。结果表明,组分中添加SnO可以引入非桥氧来改变O/P原子个数比,从而影响玻璃的结构和性能。随着SnO含量的增加,玻璃的特征温度、封接温度和耐水性能提高,热膨胀系数降低。

| Abstract: | Sealing glass is widely used in vacuum microelectronics,aerospace,automobile and other industrial fields due to its good heat resistance,high chemical stability and mechanical strength.Phosphate glass has the characteristics of low cost,low characteristic temperature and low stability,which is often used to prepare sealing glass.The glass with composition of (60-x)SnF2-xSnO-35P2O5-5WO3 (x=0%,5%,10%,15%,20%,mass fraction) was prepared by high temperature melting method.The effect of SnO content on the structure and performance of the glass was studied.The internal structure of the glass was characterized by IR,and the thermal expansion coefficient and characteristic temperatures of the glass were measured.The results show that the addition of SnO to the composition introduces non-bridging oxygen to change the O/P atomic ratio,thereby affecting the glass structure and performance.With the increase of SnO content,the characteristic temperature,sealing temperature and water resistance of the glass are improved,and the coefficient of thermal expansion decreases. |
