Abstract
Alkali-doped and alkali-free boroaluminosilicate glasses that include barium oxide and the network formers SiO, BO, and AlO. The glasses may be doped with up to about 1 mol % of LiO, NaO, and/or KO. The glass may, in some embodiments, have a Young's modulus of less than about 61 GPa and/or a coefficient of thermal expansion, averaged over a temperature range from about 20° C. to about 300° C., of less than about 40×10/° C. These glasses may be used as a cover glass for electronic devices, a color filter substrate, a thin film transistor substrate, or an outer clad layer for a glass laminate.
