Abstract
Official abstract text for this publication.
Provided is a glass composition comprising a glass frit containing P 2 O 5 , BaO, ZnO, group I-based oxide and group II-based oxide, wherein the P 2 O 5 is contained in an amount of 20 wt % to 55 wt % based on a total weight of the glass frit, wherein each of the BaO and ZnO is contained in an amount of 2 to 30% by weight based on the total weight of the glass frit, wherein the group I-based oxide is contained in an amount of 5 to 20% by weight based on the total weight of the glass frit, wherein the group II-based oxide is contained in an amount of 1 to 15% by weight based on the total weight of the glass frit.
First claim
Opening claim text (preview).
What is claimed is: 1. A glass composition comprising a glass frit containing Phosphorus Pentoxide (P 2 O 5 ), Barium Oxide (BaO), Zinc Oxide (ZnO), Silicon Dioxide (SiO 2 ), Boron Oxide (B 2 O 3 ), Aluminum Oxide (Al 2 O 3 ), Zirconium Dioxide (ZrO 2 ), Stannous Oxide (SnO), Titanium Dioxide (TiO 2 ), Calcium oxide (CaO), Magnesium Oxide (MgO) and group I-based oxide, wherein the P 2 O 5 is contained in an amount of 20 wt % to 55 wt % based on a total weight of the glass frit, wherein each of the BaO and ZnO is contained in an amount of 2 to 30% by weight based on the total weight of the glass frit, wherein the group I-based oxide is contained in an amount of 5 to 20% by weight based on the total weight of the glass frit, wherein the Calcium oxide (CaO) and Magnesium oxide (MgO) is contained in an amount of 1 to 15% by weight based on the total weight of the glass frit, wherein the SiO 2 is contained in an amount of 1 to 20% by weight based on the total weight of the glass frit, wherein the B 2 O 3 is contained in an amount of 0.1 wt % to 10 wt % based on the total weight of the glass frit, wherein each of the Al 2 O 3 and ZrO 2 is contained in an amount of 1 wt % to 20 wt % based on the total weight of the glass frit, and wherein each of the SnO and TiO 2 is contained in an amount of 0.1 wt % to 5 wt % based on the total weight of the glass frit. 2. The glass composition of claim 1 , wherein the group I-based oxide includes at least one of Na 2 O and K 2 O. 3. The glass composition of claim 1 , wherein the glass frit further contains an adhesion enhancing component, wherein the adhesion enhancing component is contained in an amount of 0.1% to 5% by weight relative to the total weight of the glass frit, wherein the adhesion enhancing component includes at least one metal oxide selected from Co 3 O 4 , NiO, Fe 2 O 3 and MnO 2 .
