Alkali metal-free aluminoborosilicate glass and its use

摘要

An alkali metal-free aluminoborosilicate glass is described which has the following composition (in % by weight based on oxide): SiO2 57-60; B2O3 6.5-9.5; Al2O3 14-17.5; MgO 5-8; CaO 1-4; SrO 5-8; BaO 0-3.5; with MgO+CaO+SrO+BaO 15-17; ZrO2 0.4-1.5; TiO2 0.4-1.5; CeO2 0.1-0.5; SnO2 0.2-1. The glass is particularly suitable for use as a substrate glass in display technology.
