Abstract
The embodiments described herein relate to low temperature moldable sheet forming glass compositions and glass articles formed from the same. In various embodiments, the glass composition comprises from about 60 mol. % to about 67 mol. % SiO, from about 6 mol. % to about 11 mol. % BO, from about 4.5 mol. % to about 11 mol. % LiO, AlO, NaO, and KO. The glass composition also includes greater than about 2 mol. % RO, where RO are divalent metal oxides, and RO from about 14 mol. % to about 20 mol. %, where RO are alkali metal oxides. The glass composition also has a glass transition temperature Tof less than about 500° C., a softening point of less than about 650° C., and a coefficient of thermal expansion (CTE) of less than about 85×10K.
