摘要：
The chemically resistant borosilicate glass has the following composition (in % by weight): SiO2, 67-74; B2O3, 5-10; Al2O3, 3-10; Li2O, 0-4; Na2O, 0-10; K2O, 0-10; MgO, 0-2; CaO, 0-3; SrO, 0-3; BaO, 0-3; ZnO, 0-3; ZrO2, 0-3; CeO2, 0-1; with ΣLi2O+Na2O+K2O=0.5 to 10.5 and ΣMgO+CaO+SrO+BaO+ZnO=0-6. The borosilicate glass is characterized by a composition including 0 to 10% of at least one of TiO2, Bi2O3 and MoO3 and a sum total of TiO2+Bi2O3+MoO3 of 0.1 to 10%. This glass is obtained from the melt under oxidative conditions. The glass is useful in gas discharge lamps, such as Xenon lamps and fluorescent lamps, and display devices, flat structured backlighting devices, and glass-to-metal seals with Mo, Wo and Ni—Fe—Co alloys.
