Abstract
The embodiments described herein relate to glass articles that include mechanically durable glass compositions having high liquidus viscosity. The glass articles may include glass compositions having from 50 mol. % to 80 mol. % SiO; from 7 mol. % to 25 mol. % AlO; from 2 mol. % to about 14 mol. % LiO; 0.4 mol. % PO; and less than or equal to 0.5 mol. % ZrO. The quantity (AlO(mol. %)-RO (mol. %)-RO (mol. %)) is greater than zero, where RO (mol. %) is the sum of the molar amounts of LiO, NaO, KO, RbO, and CsO in the glass composition and RO (mol. %) is the sum of the molar amounts of BeO, MgO, CaO, SrO, BaO, and ZnO in the glass composition. A molar ratio of (LiO (mol. %))/(RO (mol. %)) may be greater or equal to 0.5. In embodiments, the glass composition may include BO. The glass compositions are fusion formable and have high damage resistance.
