Abstract
A hermetic sealing glass composition comprising an inorganic component which consists essentially of from 60 to 100 wt % of a glass powder, from 0 to 30 wt % of a filler and from 0 to 10 wt % of a pigment, wherein said glass powder consists essentially of from 30 to 45 wt % of SiO.sub.2, from 11 to 25 wt % of Al.sub.2 O.sub.3, from 11 to 25 wt % of ZnO, from 11 to 25 wt % of B.sub.2 O.sub.3, from 0.05 to 10 wt % of ZrO.sub.2, from 0.1 to 10 wt % of at least one of La.sub.2 O.sub.3, from 0.1 to 7 wt % of BaO, SrO, or CaO+MgO, from 0.1 to 7 wt % of at least one Li.sub.2 O, +Na.sub.2 or K.sub.2 O, from 0.1 to 5 wt % of at least one CeO.sub.2, +TiO.sub.2 or SnO.sub.2, from 0 to 5 wt % of PbO and from 0 to 5 wt % of at least one metal oxide selected from the group consisting of oxides of Co, Ni, Cr, Mn, Fe and Cu.
