Abstract
A glass substrate formed from a glass composition is disclosed. In embodiments, the composition comprises: from 60 mol. % to 75 mol. % SiO; from 2 mol. % to 15 mol. % LiO; from 1.9 mol. % to 15 mol. % YO; and at least one of BOand NaO. BO+NaO is from 2 mol. % to 13 mol. %. YO+AlOis from 10 mol. % to 24 mol. %. A ratio RO/AlOis from 0.5 to 4, where RO is a total concentration of LiO, NaO, KO, RbO, and CsO. (RO+RO)/AlOis from 0.5 to 4.5, where RO is a total concentration of BeO, MgO, CaO, SrO, and BaO. The glass substrate has a Young's modulus from 75 gigapascals (GPa) to 110 GPa. The glass substrate is ion exchangeable to form a strengthened glass article.
