The objective of the present invention is to provide: a glass composition, which is useful for forming a glass ceramic that has thermal expansion characteristics suitable for sealing of a ceramic member and the like, and which exhibits good wettability with respect to the surface of the ceramic member and the like at the time of firing; and a sealing material. A glass composition for sealing, which has a compositional ratio wherein, in terms of oxides, SiO2 is 14-21% by mass, Al2O3 is 0-12% by mass, B2O3 is 17-24% by mass, ZnO is 29-51% by mass and MgO is 7-16% by mass, and the like are provided in order to achieve the above-mentioned objective. |
