Abstract:
A glass article including, on an oxide basis, from 60 mol % to 74 mol % SiO2, from 7 mol % to 18 mol % Al2O3, from 3 mol % to 16 mol % B2O3, from 0 mol % to 6 mol % Na2O, from 0 mol % to 5 mol % P2O5, from 5 mol % to 11 mol % Li2O, less than or equal to 0.2 mol % SnO2, and from 0.5 mol % to 6.5 mol % divalent cation oxides. The glass article has a molar ratio of Al2O3:(R2O+RO) greater than or equal to 0.9, where R2O is a sum of alkali metal oxides in mol % and RO is a sum of divalent cation oxides in mol %.
