Abstract
A glass composition includes about 60 mol. % to about 80 mol. % SiO2, 0 mol. % to about 11 mol. % Al2O3, about 4.0 mol. % to about 12 mol. % B2O3, about 0.5 mol. % to about 20 mol. % of K2O, 0 mol. % to about 18.5 mol. % MgO, and 0 mol. % to about 1 mol. % SnO2. The glass composition has a range of CTE, which can be adjusted based on the composition, and can be used for display applications.
