Abstract:
According to one embodiment, a glass-ceramic composition may include from about 60 mol. % to about 75 mol. % SiO2; from about 5 mol. % to about 10 mol. % Al2O3; from about 2 mol. % to about 20 mol. % alkali oxide R2O, the alkali oxide R2O including Li2O and Na2O; and from 0 mol. % to about 5 mol. % alkaline earth oxide RO, the alkaline earth oxide RO including MgO. A ratio of Al2O3 (mol. %) to the sum of (R2O (mol. %)+RO (mol. %)) may be less than 1 in the glass-ceramic composition. A major crystalline phase of the glass-ceramic composition may be Li2Si2O5. A liquidus viscosity of the glass-ceramic composition may be greater than 35 kP. The glass-ceramic composition may be used to form the glass clad layer(s) of a laminated glass article.
