摘　　要：封接玻璃是一种用于连接、密封同种或异种材料的特种玻璃。近年来多种类、高质量金属间封接需求递增,要求开发更高膨胀系数的封接玻璃。详细介绍了线膨胀系数高于90×10^(-7)℃^(-1)的封接玻璃的国内外研究现状,分析了高膨胀系数封接玻璃的发展趋势。无铅结晶型封接玻璃可以达到更高的线膨胀系数,足以适配常用金属,无铅封接玻璃综合性能不亚于含铅封接玻璃,能够实现对含铅封接玻璃的替代,具有更大的发展优势。Sealing glass is used to connect and seal same or different kinds of materials.The development of sealing glass with higher expansion coefficient(CTE)is needed due to the recent request for high-quality sealing between multiple metals.This review introduces domestic and international research status of sealing glass with CTE higher than 90×10^(-7)℃^(-1),and discusses the development trend of sealing glass with high CTE.Lead-free crystalline sealing glasses can match more metals by their possibility of achieving higher CTE.The performance of lead-free sealing glass is not inferior to lead-contained sealing glass and able to replace lead-contained sealing glass in the future.Lead-free crystalline sealing glasses has greater development advantages.
