摘要： Glass compositions and glass articles comprising the glass compositions are disclosed. In one embodiment, a glass composition includes from about 65 mol. % to about 70 mol. % SiO2; from about 9 mol. % to about 14 mol. % Al2O3; and from about 0 mol. % to about 11 mol. % B2O3 as glass network formers. The glass composition also includes from about 5 mol. % to less than 10 mol. % alkali oxide R2O, wherein R is at least one of Li, Na, and K. The glass composition also includes from about 3 mol. % to about 11 mol. % of divalent oxide MO, wherein M is at least one of Mg, Ca, Ba, SrO and Zn. The glass composition has a coefficient of thermal expansion which is less than or equal to 55×10-7/° C. and is amenable to strengthening by ion-exchange. The glass composition is well suited for use as the glass cladding layers of a laminated glass article.
