Abstract
A glass composition is provided that is capable of being ion exchanged to produce high central tension values. The glass composition includes SiO, LiO, and CaO. Glass-based articles formed by ion-exchanging glass-based substrates formed from the glass composition are also provided. The glass-based articles are characterized by a maximum central tension of greater than or equal to 150 MPa, and this maximum central tension value may be achieved by ion exchanging in a sodium containing molten salt bath. The glass-based articles may be utilized in consumer electronic devices.
