    摘要: The borosilicate glass of the invention is highly resistant to solarization, because it is free of CeO2. Also it contains 0.01 to 0.05 wt. % of Fe2O3 and 0.05 to 0.8 wt. % of TiO2. This borosilicate glass is especially advantageous for production of flash tubes, gas discharge lamps, and fluorescent tubes for brake lights and display backlights.

    摘要: The process of producing a refined borosilicate glass includes preparing a glass batch with a composition in wt. % on the basis of oxide content of SiO2, 65-82; Al2O3, 2-8; B2O3, 5-13; MgO+CaO+SrO +BaO+ZnO, 0-7; ZrO2, 0-2; and Li2O+Na2O+K2O, 3-10; adding 0.05 wt. % to 0.6 wt. % of sulfate(s) expressed as SO3 to the glass batch as the refining agent; melting the glass batch including the refining agent to form melted glass; and then hot-shaping the borosilicate glass. The refining agent may also include from 0.01 wt. % to 0.6 wt. % of F− or from 0.015 wt. % to 0.6 wt. of Cl−. The sulfate is preferably an alkali metal and/or alkaline earth metal sulfate or sulfates.

    摘要: A long life, halogen cycle, incandescent lamp (30) for operation in excess of 85 volts. The lamp comprises a transparent glass envelope (34) having sealed therewithin a tungsten filament (45); a pair of electrical lead-ins (42, 44) connecting the filament and extending exteriorly of the envelope for connection to a supply voltage greater than 100 V; and a fill gas within the envelope, including a halogen, at a pressure of at least three atmospheres. The envelope is constructed of a five component alkaline earth aluminosilicate glass having a composition consisting essentially of, in weight percent from >58 to about 64% SiO2, from about 14 to about 17% Al2O3; from 0 to about 1% B2O3, from 1 to about 6% MgO, from about 6 to about 12% CaO, from about 7 to about 17% BaO and from 0 to about 1.5% ZrO2.
