摘要
用DSC、IR、XRD等研究了GeO2添加量对PbO-B2O3—ZnO系玻璃结构及性能的影响．结果表明,在PbO—B2O3-ZnO系封接玻璃中,引入0．4-2．0wt％的GeO2可有效地抑制玻璃析晶,降低封接温度． GeO2含量为0．7wt％左右时,玻璃稳定性最好,封接温度最低, 仅为400℃,有利于低温封接．通过引入GeO2可在一定范围内调节PbO-B2O3-ZnO系封接玻璃的热膨胀系数．
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.
