%X Through a study on Na corrosion of Al_2O_3/Nb seal interface, itis shown that the main factor influencing the Al_2O_3/Nb seal and the lifetime ofhigh pressure natrium lamp is the interface bonding between glass seal and Nb. The microstructure of interface of high pressure natrium lamp with differentlifetime has been studied by means of TEM, and the influence of interface struc-ture on the quality of Al_2O_3/Nb seal has been revealed. Based on the thermodyna-mic analysis and Pask theory of metal/ceramic interface bonding, the physicoche-mical process of glass seal/Nb interfaces and bonding mechanism during sealing hasalso been discussed.
