And then the effects of compositions on the mechanical performance, characteristic temperatures, thermal expansion and chemical stability of the glass were discussed. Researches on lead borate sealing glasses show that PbO/B2O3 ratio exerts the most important effect on glass network. ZnO is beneficial to stabilize the glass against devitrification . Bi2O3 has little effects on the sealing temperature, while it helps to adjust the thermal expansion coefficient of lead borate glasses in a definitive range. When 0.5～4 mol% GeO2 is introduced, the glass possesses the highest stability and lowest sealing temperature (400 ?C), which is desirable for low-temperature sealing.
