Beschreibung
Zusammenfassung:	Embodiments of the invention relate to a glass composition with improved chemical and mechanical durability and a glass article formed by the glass composition. In an embodiment, the glass composition may include from about 70-78 mol% of SiO2, about 3-13 mol% of alkaline earth oxide, X mol% of Al2O3, and Y mol% of alkali oxide. The alkali oxide may include Na2O in an amount greater than about 8 mol%. The ratio of Y:X may be greater than 1. The glass composition may be free of boron and compounds of boron. In some embodiments, the glass composition may be free of phosphorus and phosphorus compounds. The glass article formed by the glass composition may have acid resistance of at least the S3 level according to the DIN12116, alkaline resistance of at least the A2 level according to the TSO695, and HGAI type hydrolytic resistance according to the ISO 720.
