摘　　要：SnO-ZnO-P2O5(SZP)三元系统玻璃是一种很好的封接材料,在低温(<500℃)封接应用中有潜力替代PbO-ZnO-B2O3和PbO-ZnO-SiO2封接玻璃以克服铅对人体以及环境的危害。本研究找出了SZP三元系统的玻璃形成区,研究了玻璃的的转变温度与组成的关系。考虑到SZP系统玻璃的热稳定性及化学稳定性,向SZP系统中引入了SiO2组成,测试了其热膨胀系数(CTE)和转变温度Tg,并研究了组成与热膨胀系数的关系。Glasses in the SnO -ZnO -P2O5 （SZP） ternary system were studied on potential replacements to PbO - ZnO - B2O3 or PbO - ZnO - SiO2 frits for low temperature （ 〈 500℃ ） sealing applications to eliminate the harm of Pb to human body and environment. An area of glass formation was found in the SZP ternary system. The relationship of SnO - ZnO - P2O5 glasses between composition and transition temperature have been studied. In order to improve chemical durability and thermal stability the SiO2 was added to these SZP glasses. The coefficient of thermal expansion （CTE） and transition temperature（Tg） of these glasses were tested. Effects of glass composition on coefficient of thermal expansion have also been determined.
