Certain example embodiments relate to improved seals for glass articles. Certain example embodiments relate to a composition used for sealing an insulted glass unit. In certain example embodiments the composition includes vanadium oxide, barium oxide, zinc oxide, and at least one additional additive. For instance, another additive that is a different metal oxide or different metal chloride may be provided. In certain example embodiments, a vacuum insulated glass unit includes first and second glass substrates that are sealed together with a seal that includes the above-described composition.

The gas adsorbent of one aspect according to the present invention includes is included in the glass panel unit. The gas adsorbent includes: a substrate made of fiber or a porous substance, of inorganic material; and a liquid containing a getter attached to the substrate.

The invention relates to a process for manufacturing a vacuum insulated glazing wherein the glazing is assembled in a single stage by supplying glass panes, metallic spacers and corner and frame metallic seal elements which are brazed onto adhesion layers previously deposited onto the edge region areas of the glass panes.

The present invention relates to a glass, in particular a glass for the joining of glass panes for the production of vacuum insulating glasses at processing temperatures ≦420° C., to the corresponding composite glass, and to the corresponding glass paste. Moreover, the present invention relates to a vacuum insulating glass produced using the glass paste according to the invention, to the production process thereof, and to the use of the inventive glass and/or composite glass, and glass paste. The glass according to the invention is characterized in that it comprises the following components, in units of mol-%: V.sub.2O.sub.5 5-58 mol-%,Te0.sub.2 40-90 mol-%, and at least one oxide selected from ZnO 38-52 mol-%, or Al.sub.2O.sub.3 1-25 mol %, or MoO.sub.3 1-10 mol-%, or WO.sub.3 1-10 mol-%, or a combination thereof.

Methods of making a vacuum insulating glass (VIG) window unit, including edge sealing techniques relating to the same, are provided. Certain example embodiments relate to providing an infrared (IR) absorbing element(s) such as a clip or clamp proximate an edge portion of a VIG assembly during formation of an edge seal. The IR absorbing element(s) absorb applied IR radiation and heat up during an edge seal formation process. Because the IR absorbing element(s) is/are thermally conductive and in contact with at least one of the glass substrates the element(s) causes/cause heat to be transferred from the element(s) to the adjacent glass substrate(s) and to the adjacent edge seal material thereby helping the edge seal material to heat up faster during the edge seal formation process and keeping other areas of glass at lower temperatures.

A glass panel unit assembly includes a pair of glass substrates arranged to face each other, a peripheral wall, a partition, an air passage, and an evacuation port. The peripheral wall has a frame shape and is provided between the pair of glass substrates. The partition partitions an internal space, surrounded with the pair of glass substrates and the peripheral wall, into a first space and a second space. The air passage connects the first space and the second space together. The evacuation port connects the second space to an external environment. The partition has a broader width than the peripheral wall.

Vacuum insulating glass (VIG) units, edge seals for VIG units and methods for forming the edge seals are provided. The VIG units include an edge seal that includes a viscous material, which serves to restrict the rate at which gas permeates into a vacuum space defined between the glass sheets of the VIG unit. The edge seals are configured to allow the glass sheets to move laterally relative to one another when the glass sheets experience differential thermal strain and further configured such that viscous shear occurs within at least a portion of the viscous material when there is relative lateral movement between the glass sheets.

An insulating glazing system may include: at least two glass panes and a spacer element, wherein the at least two glass panes and the spacer element define a closed volume; a light ray shielding device within the closed volume, defining: transparent areas allowing passage of incident light rays with a given angle of incidence, whereas light rays having other angles of incidence are unable to pass through the transparent areas; and non-transparent areas configured to block the passage of the incident light rays, the non-transparent areas defining first and second surfaces; and a support means connected to the spacer element and operably associated with the shielding device. The shielding device may include a layer having retroreflective properties. The layer may at least partially cover one or both of the first and second surfaces of at least one of the areas of the non-transparent areas of the shielding device.

The present invention discloses a vacuum plate and a method for manufacturing it. The vacuum plate comprises at least two layers of plate, a plurality of support structures with different heights, and an organic film. The plates in adjacent layers are separated by a plurality of the support structures with different heights, peripheries of the at least two layers of plate are connected and sealed via a sealing mixture; and the peripheries of the at least two layers of plate and the outside of the sealing mixture are covered with the organic film. According to surface undulation of the plate, the supporting structures with corresponding heights are arranged on corresponding positions between the layers of plate, and the heights of the support structures match with the spacings at corresponding positions in the vacuum plate, so that each support structure can be clamped by the upper and the lower plate layers, and effectively plays a supporting role, thereby reducing the security risk from damage of the vacuum plate.

A vacuum glazing includes a vacuum layer formed between a first glazing and a second glazing, a spacer provided in the vacuum layer, a frame provided at edge portions of the first and second glazings, and a sealant interposed between the frame and surfaces of the first and second glazings to perform sealing of the vacuum layer. The insulating performance of the vacuum glazing is improved.
