ALKALINE-EARTH ALUMINOSILICATE GLASS AND USE THEREOF

摘要

The invention relates to an alkaline-earth aluminosilicate glass with the following composition (in wt. %, based on oxide content): SiO2 > 58 - 62; B2O3 0 5.5; Al2O3 13.5 17.5; MgO 0 - 7; CaO 5.5 - 14; SrO 0 - 8, BaO 6 - 14; ZrO2 0 - 2; CeO2 0.001 0.5; TiO2 0.01 - 2. The glass is particularly suitable for use as a bulb material for halogen light bulbs.
