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 vacuum insulated glass unit includes first and second glass substrates that are sealed together with a seal that includes the above-described composition.
Claims23
A method of making a vacuum insulated glass (VIG) window unit, the method comprising:
- providing a sealing material on, directly or indirectly, a first glass substrate and/or a second glass substrate, the material comprising at least a fit material and a binder solution;
- wherein the first and second glass substrates are thermally tempered;
- providing the first and second glass substrates in substantially parallel, spaced apart relation to one another, where the sealing material is provided on at least one of the glass substrates, and a gap being defined between the first and second substrates, and wherein at least a portion of the sealing material is located between the first and second glass substrates;
- applying energy to the frit material so as to melt the frit material at least at a melting temperature, the melting temperature being less than about 400 degrees C.,
- wherein the applying of the energy substantially burns off the binder solution of the sealing material, and wherein after the energy is applied the first and second glass substrates are sealed to each other directly or indirectly in making the VIG window unit, and
- wherein the frit material is formed from a base composition including:
- Ingredient
- Normalized Mole %
- vanadium oxide
- ~45-50%,
- barium oxide
- ~20-23%, and
- zinc oxide
- ~19-22%,
- tellurium oxide
- 1-10%,
- molybdenum oxide
- 1-6%,
- wherein the vanadium oxide, the barium oxide, and the zinc oxide are the largest three elements making up the base composition of the fit material.
