| 内容： | A sealing composition for ceramic discharge vessels is described. The sealing composition contains about 20 to about 40 mole percent MgO, about 20 to about 45 mole percent Y2O3, and about 20 to about 60 mole percent Al2O3 and has a melting point of less than about 1800 DEG C., and preferably from about 1700 DEG C. to about 1800 DEG C. The sealing composition may be used for making ceramic-to-ceramic or ceramic-to-metal seals in ceramic discharge vessels. |
