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.

1. 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 secon
1. 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, andwherein the frit material is formed from a base composition including: IngredientNormalized Mole %vanadium oxide~45-50%,barium oxide~20-23%, andzinc oxide~19-22%,tellurium oxide1-10%,molybdenum oxide1-6%, 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. 2. The method of claim 1, wherein the applying of the energy to the frit material includes: holding a temperature of the frit material at a first temperature for a first period of time; andincreasing the temperature of the frit material to the melting temperature over a second period of time. 3. The method of claim 2, wherein the first period of time is greater than the second period of time. 4. The method of claim 3, wherein the first period of time is between about 2 and 15 minutes. 5. The method of claim 3, wherein the first period of time is between about 5 and 10 minutes. 6. The method of claim 2, wherein the second period of time is less than about 5 minutes. 7. The method of claim 3, wherein the second period of time is less than about 3 minutes. 8. The method of claim 7, wherein the first temperature is less than about 300 degrees C. 9. The method of claim 1, wherein prior to applying the energy, a ratio between the frit material and the binder solution is about 5 to 1. 10. The method of claim 1, wherein the binder solution includes polypropylene carbonate or polyethylene carbonate. 11. The method of claim 1, wherein the base composition includes at least four oxide-, chloride-, and/or fluoride-based additives. 12. The method of claim 1, further comprising evacuating the gap between the first and second glass substrates to a pressure less than atmospheric pressure after a seal has been formed via at least said frit material. 13. 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 frit 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, andwherein the frit material is formed from a base composition comprising: IngredientNormalized Mole %vanadium oxide 35-55%barium oxide 15-35%zinc oxide<=25%tellurium oxide 1-10%molybdenum oxide 1-6%niobium oxide0.5-6%, 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. 14. The method of claim 13, wherein the applying of the energy to the frit material includes: holding a temperature of the frit material at a first temperature for a first period of time; andincreasing the temperature of the frit material to the melting temperature over a second period of time. 15. The method of claim 14, wherein the first period of time is greater than the second period of time. 16. The method of claim 15, wherein the first period of time is between about 2 and 15 minutes. 17. The method of claim 16, wherein the first period of time is between about 5 and 10 minutes. 18. The method of claim 14, wherein the second period of time is less than about 5 minutes. 19. The method of claim 18, wherein the second period of time is less than about 3 minutes. 20. The method of claim 14, wherein the first temperature is less than about 300 degrees C. 21. The method of claim 13, wherein prior to applying the energy, a ratio between the frit material and the binder solution is about 5 to 1. 22. The method of claim 13, wherein the binder solution includes polypropylene carbonate or polyethylene carbonate. 23. The method of claim 13, further comprising evacuating the gap between the first and second glass substrates to a pressure less than atmospheric pressure after a seal has been formed via at least said frit material.
