摘要
无铅低温封接玻璃由于具有绿色安全、成本低、封接温度低等优势,被广泛应用于航空航天、电真空、集成电路等领域.在磷酸盐、钒酸盐、硼酸盐和铋酸盐等多种封接玻璃体系中,因铋与铅具有相似的性质特点,使得铋酸盐玻璃成为最有可能替代铅酸盐玻璃的绿色玻璃钎料.综述了铋酸盐玻璃的成分和性能调控、网络结构的研究现状,介绍了 目前使用铋酸盐封接玻璃进行金属、陶瓷同质/异质材料连接的研究进展,最后对未来的发展趋势进行了展望.
Abstract
Lead-free low-temperature sealing glass is widely used in aerospace,electric vacuum,integrated circuits and other fields due to its advantages of green safety,low cost and low sealing temperature.In phosphate,vanadate,borate and bismuthate and other sealing glass systems,because bismuth and lead have similar properties,bismuthate glass has become the green glass filler metal that is most likely to replace lead-acid glass.The research status of composition,property regulation and network structure of bismuthate glass is reviewed,and the research progress on homogeneous/heterogeneous materials between metal and ceramics using bismuthate sealing glass is introduced.Finally,the future development trend is prospected.
