초록

The invention is directed to an aluminosilicate glass containing alkaline earth metals for lamp bulbs which have molybdenum components and bulb temperatures of greater than 650.degree. C. The glass has a composition in percent by weight on oxide basis as follows: SiO.sub.2 >58-62; Al.sub.2 O.sub.3 15-17.5; B.sub.2 O.sub.3 0.2-0.7; MgO 0-<1; CaO 5.5-14; SrO 0-8; BaO 6-10; ZrO 0.05-1.0; CeO.sub.2 0-0.3; TiO.sub.2 0-0.5; Br.sup.- 0-0.6 where .SIGMA. RO 21-24; (MgO+CaO+SrO)/BaO 1.45-1.75; and an alkali metal content of <0.03% by weight and a water content of...
