Alkali-doped and alkali-free boroaluminosilicate glass

Alkali-doped boroaluminosilicate glasses are provided. The glasses include the network formers SiO2, B2O3, and Al2O3. The glass may, in some embodiments, have a Young's modulus of less than about 65 GPa and/or a coefficient of thermal expansion of less than about 40×10−7/° C. The glass may be u...

More Information
Summary:Alkali-doped boroaluminosilicate glasses are provided. The glasses include the network formers SiO2, B2O3, and Al2O3. The glass may, in some embodiments, have a Young's modulus of less than about 65 GPa and/or a coefficient of thermal expansion of less than about 40×10−7/° C. The glass 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.
