Abstract

A glass frit having a low melting point containing (A) Ag 2 O, (B) V 2 O 5 , and (C) at least one first oxide selected from the group consisting of MoO 3 , ZnO, CuO, TiO 2 , Bi 2 O 3 , MnO 2 , MgO, Nb 2 O 5 , BaO and P 2 O 5 . The glass frit preferably contains 40 to 70% by mass of (A), 10 to 40% by mass of (B), and 0.5 to 30% by mass of (C) with respect to the total mass in terms of oxides. Furthermore, the glass frit preferably has a mass ratio (Ag 2 O/V 2 O 5 ) of (A) to (B) of 1.8 to 3.2.

First claim

The invention claimed is:

1. A glass frit which does not contain lead, arsenic, antimony or tellurium, the glass frit comprising (A) Ag 2 O, (B) V 2 O 5 , and (C) at least two first oxides consisting of a combination of at least two oxides selected from the group consisting of MoO 3 , ZnO and CuO.

2. The glass frit according to claim 1 , wherein component (C) consists of a combination of oxides selected from the group consisting of MoO 3 and ZnO; MoO 3 and CuO; and ZnO and CuO.

3. The glass frit according to claim 1 , wherein component (C) consists of a combination of MoO 3 , ZnO and CuO.

4. The glass frit according to claim 1 , wherein the mass ratio (Ag 2 O/V 2 O 5 ) of (A) to (B) is 1.8 to 3.2.

5. The glass frit according to claim 1 , wherein (A) is in an amount of 40 to 70% by mass, (B) is in an amount of 10 to 40% by mass, and (C) is in an amount of 0.5 to 30% by mass, with respect to the total mass in terms of oxides.

6. The glass frit according to claim 5 , wherein (C) is in an amount of 0.5 to 15% by mass, with respect to the total mass in terms of oxides.

7. The glass frit according to claim 1 , further comprising (D) at least one second oxide selected from the group consisting of SiO 2 , Al 2 O 3 , SnO, WO 3 and Fe 2 O 3 .

8. The glass frit according to claim 7 , wherein (D) is in an amount of greater than 0 to 15% by mass with respect to the total mass in terms of oxides.

9. A glass frit which does not contain lead, arsenic, antimony or tellurium, the glass frit consisting essentially of (A) Ag 2 O, (B) V 2 O 5 , and (C) at least one first oxide consisting of MoO 3 or a combination of at least two oxides selected from the group consisting of MoO 3 , ZnO and CuO.

10. The glass frit according to claim 9 , wherein (C) consists of two first oxides selected from the group consisting of MoO 3 , ZnO and CuO.

11. The glass frit according to claim 9 , wherein (C) consists of MoO 3 .

12. The glass frit according to claim 9 , wherein (C) consists of MoO 3 and ZnO.

13. The glass frit according to claim 12 , wherein a mass ratio (MoO 3 :ZnO) of MoO 3 to ZnO in (C) is 12:1 to 1:12.

14. The glass frit according to claim 9 , wherein (C) consists of MoO 3 and CuO.

15. The glass frit according to claim 14 , wherein a mass ratio (MoO 3 :CuO) of MoO 3 to CuO in (C) is 12:1 to 1:10.

16. The glass frit according to claim 9 , wherein (C) consists of ZnO and CuO.

17. The glass frit according to claim 16 , wherein a mass ratio (ZnO:CuO) of ZnO to CuO in (C) is 12:1 to 1:12.

18. The glass frit according to claim 9 , wherein (C) consists of MoO 3 , ZnO, and CuO.

19. The glass frit according to claim 18 , wherein a mass ratio (MoO 3 :total amount of CuO and ZnO) of MoO 3 to the total amount of ZnO and CuO in (C) is 12:1 to 1:12.

20. A glass frit which does not contain lead, arsenic, antimony or tellurium, the glass frit consisting essentially of (A) Ag 2 O; (B) V 2 O 5 ; (C) at least one first oxide consisting of MoO 3 or a combination of at least two oxides selected from the group consisting of MoO 3 , ZnO and CuO; and (D) at least one second oxide selected from the group consisting of SiO 2 , Al 2 O 3 , SnO, WO 3 and Fe 2 O 3 .

21. The glass frit according to claim 18 , wherein (C) consists of MoO 3 .
