Beschreibung
Zusammenfassung:	This glass composition contains, as indicated in mol%, from 58% to less than 70% SiO2, 0-14% B2O3, 10-16% Al2O3, 0-12.5% MgO, 0-11% CaO, 0-3% SrO, 0-3% ZnO, 4.5-11% Li2O, 0-2% Na2O, 2-7% K2O, 0-0.8% TiO2, 0-0.5% ZrO2, and 0-0.2% SnO2, with Li2O + Na2O + K2O being within the range of 6.5-13%. This glass composition is suited to production by the float method, and is also suited to chemical strengthening. This glass composition has a low thermal expansion coefficient, and has properties suitable for substrate glass for displays.
