Effects of GeO2 on Structure and Properties of PbO-B2O3-ZnO Glass

doi:10.3724/SP.J.1077.2006.00533

Abstract

Abstract:

The effects of GeO₂ on the structure and properties of PbO-B₂O₃-ZnO glass were investigated by DSC, IR, XRD. Results indicate that the addition of GeO2(0.4～2wt%) to PbO-B₂O₃-ZnO glass can suppress crystallization and decrease sealing temperature. When the content of GeO₂ is 0.7 wt%, the stability of glass is the best and the sealing temperature is the lowest (400 ℃), which is a desirable material for low-temperature sealing. The coefficient of thermal expansion of PbO-B₂O₃-ZnO glass can be adjusted by the addition of GeO₂.

Key words: PbO-B2O3-ZnO glass, sealing temperature, crystallization activation energy, thermal expansion
