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-
摘要:
The present invention generally relates to a method of making halogen lamps and halogen lamp bulbs, as well as other analogous lamps and objects. The present invention also relates to apparatus used in a method of making halogen lamps and halogen lamp bulbs, as well as other analogous lamps and objects. The method minimizes contamination in the body of the glass and minimizes reaction of lamp halogen with the interior of a halogen lamp.
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.
