Abstract
The research on low-temperature lead-free glass is of great significance for the miniaturization, integration and intelligence of current electronic products, as well as environmental protection. In this article, we report the preparation of low-temperature lead-free B2O3-BaO-ZnO-SiO2-Al2O3-TeO2 glasses by a melt-quenching technique. With the increase of TeO2 content in glass, the glass transition temperature and melting temperature of sintered glass powder decrease, while its wettability and acid corrosion resistance show an increasing trend. The application of glass powder in the sintering experiment of terminal electrode slurry further proves this viewpoint. Compared with the poor sintering performance of the slurry with TeO2-free glass powder, the slurry containing TeO2 glass powder forms a very dense sintered solid, and the sintered slurry is tightly bonded to the ceramic substrate.
