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.

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, the edge sealing material comprising at least a frit material and a coefficient of thermal expansion (CTE) matching material; andapplying energy to the edge sealing material so as to melt the edge sealing material at a melting temperature,wherein the CTE matching material comprises a first element group comprising substantial sphere shapes comprising molybdenum and a second element group comprising substantial sphere shapes comprising molybdenum, wherein the first element group includes a majority of elements that are between 40 and 100 microns in size and the second element group includes a majority of elements that are larger in size than are a majority of elements of the first element group, and wherein the first element group is lower, by weight, than the second element group,wherein the frit material is formed from a base composition including: IngredientNormalized Mole %vanadium oxide~45-50%,barium oxide~20-23%, andzinc oxide~19-22%. 2. The method of claim 1, wherein a percentage, by weight, of the first element group in the CTE matching material is between about 25 and 45 percent. 3. The method of claim 2, wherein the percentage is about 35 percent. 4. The method of claim 1, wherein a percentage, by weight, of CTE matching material of the edge sealing material is between about 25 and 40 percent. 5. The method of claim 4, wherein the percentage is about 32 percent. 6. The method of claim 1, wherein a majority of elements in the first element group and a majority of the elements in the second element group are substantially spherical. 7. The method of claim 1, wherein the melting temperature of the edge sealing material is about 400 degrees C. or less. 8. The method of claim 1, wherein the edge sealing material has a flow rate that is similar to a 30 mm flow rate on a 25 mm button of the edge sealing material. 9. The method of claim 1, wherein the majority of elements of the first element group are between about 70 and 90 microns and the majority of elements of the second element group are between about 90 and 160 microns. 10. 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, the edge sealing material comprising at least a frit material and a coefficient of thermal expansion (CTE) matching material; andapplying energy to the edge sealing material so as to melt the edge sealing material at a melting temperature,wherein the CTE matching material comprises a first element group comprising substantial sphere shapes comprising molybdenum and a second element group comprising substantial sphere shapes comprising molybdenum, wherein the first element group includes a majority of elements that are between 40 and 100 microns in size and the second element group includes a majority of elements that are larger in size than are a majority of elements of the first element group, and wherein the first element group is lower, by weight, than the second element group,wherein the frit material is formed from a base composition comprising vanadium oxide, barium oxide, and zinc oxide as the three largest components of the base composition of the frit material, andwherein a percentage, by weight, of the CTE matching material, in the combination of the CTE matching material and the frit material of the edge sealing material, is between about 25 and 40 percent. 11. The method of claim 10, wherein a percentage, by weight, of the first element group in the CTE matching material is between about 25 and 45 percent of the overall weight of the CTE matching material. 12. The method of claim 10, wherein a majority of elements in the first element group and a majority of the elements in the second element group are substantially spherical. 13. The method of claim 10, wherein the melting temperature of the edge sealing material is about 400 degrees C. or less. 14. The method of claim 10, wherein the edge sealing material has a flow rate that is similar to a 30 mm flow rate on a 25 mm button of the edge sealing material. 15. The method of claim 10, wherein the majority of elements of the first element group are between about 70 and 90 microns and the majority of elements of the second element group are between about 90 and 160 microns in size.
