Diffusion of Metallic Species and their Influence on Interfacial Reactions in Glass-Ceramic-to-Metal Seals
This is a preliminary investigation aimed at assessing the influence of individual metallic elements on the sealing characteristics of glass-ceramic-to-metal seals in order to aid in the analysis of interfacial reactions in more complex practical alloy systems. In the present study, a lithium zinc silicate (LZS) glass nucleated with P2O5 has been sealed to high purity Fe, Ni and Cr metals and the resultant diffusion into the glass of each metal monitored as a function of sealing temperature and time. The initial data obtained are compared with similar data noted for multi-component alloys.
