Soft, chemically-strengthenable glasses for laminates
Abstract:
Disclosed herein are embodiments of a glass article having a glass composition. The glass composition includes SiO2 in an amount of from 63 mol % to 75 mol %, Al2O3 in an amount of from 7 mol % to 13 mol %, R2O in an amount of from 13 mol % to 24 mol %, P2O5 in an amount of from 0.1 mol % to 1.2 mol %, and a water content β-OH of 0.1 abs/mm to 0.5 abs/mm. Further, the glass composition includes at least one of MgO or ZnO. MgO is present in a range from 0 mol % to 7 mol %, and ZnO is present in a range from 0 mol % to 7 mol %. The glass article has an anneal point and a softening point, and the relationship of (anneal point+softening point)/2 is less than 685° C.
