Due to excellent properties such as thermal insulation, sound insulation, lightness and anticondensation, vacuum glass has been gradually used in energysaving building, household appliances, traffic, agriculture, etc. Especially, the vacuum glass shows broad development prospects in the field of energysaving buildings. In this paper, the development history of vacuum glass was reviewed. Then, the research foundation of vacuum glass, the major breakthrough progress and industrialization status of industrialization technology were introduced. Moreover, the sealing materials and sealing technologies of vacuum glass and the latest research progress were mainly described. Finally, the future development of sealing materials and sealing technologies in vacuum glass were prospected in order to provide reference for the basic research and industrial application of high performance vacuum glass.
