PROBLEM TO BE SOLVED: To provide a crystalline glass composition which has fluidity suitable for bonding, has a high thermal expansion coefficient after heat treatment, hardly causes deterioration in power generation characteristics of a fuel cell due to evaporation of glass components even if exposed to a high temperature for a long time and is excellent in heat resistance after bonding.SOLUTION: There is provided a crystalline glass composition which contains, by mol%, 40 to 70% of SiO(provided that 40% is excluded), 5 to 40% of MgO, 3 to 30% of CaO, 0 to 20% of SrO, 5 to 40% of BaO, 5 to 40% of ZnO, 0 to 5% of BO, 0 to 2% of AlO(provided that 2% is excluded), 0 to 15% of LaO, 0 to 1% of YO, 0 to 4% of GdO, 0 to 5% of NbOand 0 to 2% of TaO. |
