Effects of GeO_2 on Structure and Properties of PbO-B_2O_3-ZnO Glass
Source 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.
