Abstract

A novel sealing method of vacuum glazing is introduced in this study. Anodic bonding technology was used to enhance the bonding strength of the sealant of vacuum glazing. Two sheets of plane glass were sealed by V ₂O ₅-P ₂O ₅-TeO ₂ glass powder with low glass transition temperature (339.3℃) using anodic bonding-assisted low-temperature sintering. Through analyzing the results of Shear Strength test, the diagram of microstructures of the sealing bond taken by a micro Super-depth Microscopy, Scanning Electron Microscope (SEM), and Energy Dispersive Spectrometer (EDS), the best bonding treatment schedule was determined for achieving the strongest bond. The experiment results show that anodic bonding has a dramatic influence on bonding performance. When the sealing temperature and bonding time are kept constant, the shear strength of the sample increases by increasing the bonding voltage. With the bonding temperature of 470℃ and the voltage of 600 V, the air tightness of the sealed sample is 3.9 × 10− ⁹ Pa·m ³/s. The improved bonding strength can enhance life-time of vacuum glazing.
