Abstract

Certain example embodiments relate to 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 composition may be combined with a binder solution that substantially or completely burns out by the time the composition is melted. In certain example embodiments, a CTE filler is included with a frit material. 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.

Claims (5)

1. A method of making a vacuum insulated glass (VIG) unit, the method comprising:

providing first and second glass substrates in substantially parallel, spaced apart relation to one another, a gap being defined between the first and second substrates;

disposing an edge sealing material proximate to the first and/or second glass substrates; and

applying energy to the edge sealing material so as to melt the edge sealing material;

wherein the edge sealing material comprises vanadium oxide, barium oxide, and zinc oxide as the three largest components, and further comprises from 0.5 to 6% (molar %) niobium oxide.
