Abstract

The invention discloses Ce-containing low-temperature sealing glass as well as preparation and application method of the Ce-containing low-temperature sealing glass. The Ce-containing low-temperature sealing glass consists of the following raw materials: B2O3, Bi2O3, ZnO and Ce(NO3)3 in a molar ratio of (10-50):(20-40):(5-30):(0-30). Through the coordination between high-concentration Bi2O3 and B2O3, the softening temperature of glass is lowered, so that low-temperature sealing is realized; Ce<3+> in a glass network prepared by melting quenching is transformed into Ce<4+>, the transformation of Bi<3+> in glass into Bi<5+> is prevented, and the refractive index of glass is stabilized; and Ce not only can further lower the softening temperature of the sealing glass, but also can adjust the expansion factor of the glass so as to remarkably improve the sealing property of the sealing glass. Moreover, Ce remarkably reduces the surface tension of the glass, improves the interface bonding property between the sealing glass and an alloy connector and is applicable to the field of photoelectric materials and other low-temperature precise sealing. According to the invention, the preparation raw materials are simple and easily available, the cost is low, the technology is simple and feasible, and the prepared low-temperature sealing glass has good performance and stable refractive index and meets the conditions of practical utilization and industrialization.
