  • Patent number: 8778469
    Abstract: When local heating by use of laser sealing or the like is applied, the bonding strength between glass substrates and a sealing layer is improved to provide an electronic device having increased reliability. An electronic device includes a first glass substrate, a second glass substrate, and a sealing layer to seal an electronic element portion disposed between these glass substrates. The sealing layer is a layer obtained by locally heating a sealing material by an electromagnetic wave, such as laser light or infrared light, to melt-bond the sealing material, the sealing material containing sealing glass, a low-expansion filler and an electromagnetic wave absorber. In the first and second glass substrates, each reacted layer is produced to have a maximum depth of at least 30 nm from an interface with the sealing layer.

The polymeric binder system is a solid at room temperature, but melts at a temperature of from about 35° C. to about 90° C., thereby forming a flowable liquid dispersion that can be applied to a substrate (e.g., a cap wafer and/or a device wafer of a MEMS device) by screen printing. Hot-melt sealing glass compositions according to the invention rapidly re-solidify and adhere to the substrate after being deposited by screen printing. Thus, they do not tend to spread out as much as conventional solvent-based glass frit bonding pastes after screen printing. And, because hot-melt sealing glass compositions according to the invention are not solvent-based systems, they do not need to be force dried after deposition.

    Abstract: The present invention relates to a sealing glass composition for an intermediate-temperature planar SOFC, and a composition herein comprises a mixture of BaO, Al2O3, B2O3 and SiO2 in a particular mixing ratio and a metal oxide such as CeO2, Fe2O3, Mn2O3 and Cr2O3, thereby enabling the SOFC to efficiently operate at an intermediate temperature. The composition for a planar SOFC satisfies thermal properties, mechanical properties and electric properties that are required as a sealing glass for an intermediate-temperature SOFC, and also prevents the mixing between fuel gas and air, thereby being useful for the commercialization of SOFCs.

  • Patent number: 8063560
    Abstract: A hermetically sealed glass package and method for manufacturing the hermetically sealed glass package are described herein using an OLED display as an example. Basically, the hermetically sealed OLED display is manufactured by providing a first substrate plate and a second substrate plate and depositing a frit onto the second substrate plate. OLEDs are deposited on the first substrate plate. An irradiation source (e.g., laser, infrared light) is then used to heat the frit which melts and forms a hermetic seal that connects the first substrate plate to the second substrate plate and also protects the OLEDs. The frit is glass that was doped with at least one transition metal and possibly a CTE lowering filler such that when the irradiation source heats the frit, it softens and forms a bond. This enables the frit to melt and form the hermetic seal while avoiding thermal damage to the OLEDs.

  • Publication number: 20110262756
    Abstract: A coating for a reinforcing material, such as metal rebar, that increases the adhesion between the reinforcing material and a matrix, such as a cement-based mortar or concrete, in which the reinforcing material is embedded. The coating may comprise a glass frit mixed with a refractory material, such as dry Type I-II portland cement. The coating is bonded, typically by heat, to the surface of the reinforcing material. The reaction of the refractory component, e.g., portland cement, when the reinforcement, e.g., metal re-bar, is embedded in a matrix, e.g., fresh mortar or concrete, prevents the formation of soft precipitates at the interface of the matrix and its reinforcement. One coating comprises portland cement Type I-II combined with a commercial alkali-resistant glass frit. This coating is applied to a steel rebar and fired to bond to the rebar.

  • Publication number: 20110169108
    Abstract: Hot-melt sealing glass compositions that include one or more glass frits dispersed in a polymeric binder system. The polymeric binder system is a solid at room temperature, but melts at a temperature of from about 35° C. to about 90° C., thereby forming a flowable liquid dispersion that can be applied to a substrate (e.g., a cap wafer and/or a device wafer of a MEMS device) by screen printing. Hot-melt sealing glass compositions according to the invention rapidly re-solidify and adhere to the substrate after being deposited by screen printing. Thus, they do not tend to spread out as much as conventional solvent-based glass frit bonding pastes after screen printing. And, because hot-melt sealing glass compositions according to the invention are not solvent-based systems, they do not need to be force dried after deposition.
