Effect of pre-oxidization condition on glass-to-metal sealing
Source abstract
Abstract
Abstract The interfacial reaction and crystallization mechanism were evaluated in terms of the effect of pre-oxidation condition on the glass-to-metal sealing. The moderate oxidation of the alloy resulted in the formation of magnetite as the main crystalline phase in the oxide scale. The microstructural observation demonstrated that the glass-to-metal joint can be divided into four regions: the bulk metal region, the Fe depleted region, the transition region and the bulk glass region. However, higher oxidation degree of the alloy resulted in a thicker diffusion zone. The results show that the dissolution of oxide scale in glass inhibits the formation of fresnoite and enhances the formation of orthoclase. The crystallization mechanism of these two precipitate phases was discussed based on the dissolution of magnetite.
