    Abstract: High CTE glass compositions and laminated glass articles formed from the same are described. In one embodiment, a glass composition may include from about 70 mol. % to about 80 mol. % SiO2, from about 0 mol. % to about 8 mol. % Al2O3, and from about 3 mol. % to about 10 mol. % B2O3 as glass formers. The glass composition may further include alkali oxides such as from about 0 mol. % to about 2 mol. % Na2O and from about 10 mol. % to about 15 mol. % K2O. In addition, the glass composition may include from about 5 mol. % to about 6 mol. % of alkaline earth oxide. The alkaline earth oxide may include at least one of CaO, SrO, and BaO. However, the glass composition may be substantially free from MgO. The glass composition may be used in a laminated glass article, such as a laminated glass article formed by a fusion laminate process.

    Abstract: Alkali-free phosphoboroaluminosilicate glasses are provided. The glasses include the network formers SiO2, B2O3, and at least one of Al2O3 and P2O5. The glass may, in some embodiments, have a Young's modulus of less than about 78 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 38×10−7/° C. The glass may be used as a cover glass for electronic devices or as an outer clad layer for a glass laminate.
