| abstract |
The present invention aims at providing a lead-free glass composition that can be soften and flowed at a firing temperature that is equal to or lower than that of conventional low melting point lead glass. Furthermore, the present invention aims at providing a lead-free glass composition having fine thermal stability and fine chemical stability in addition to that property. The lead-free glass composition according to the present invention is characterized by comprising at least Ag 2 O, V 2 O 5 and TeO 2 when the components are represented by oxides, wherein the total content ratio of Ag 2 O, V 2 O 5 and TeO 2 is 75 mass % or more. Preferably, the lead-free glass composition comprises 10 to 60 mass % of Ag 2 O, 5 to 65 mass % of V 2 O 5 , and 15 to 50 mass % of TeO 2 . |
