ION EXCHANGEABLE LI-CONTAINING GLASS COMPOSITIONS FOR 3-D FORMING

摘要

According to one embodiment, a glass article may include SiO2, Al2O3, Li2O and Na2O. The glass article may have a softening point less than or equal to about 810° C. The glass article may also have a high temperature CTE less than or equal to about 27×10−6/° C. The glass article may also be ion exchangeable such that the glass has a compressive stress greater than or equal to about 600 MPa and a depth of layer greater than or equal to about 25μm after ion exchange in a salt bath comprising KNO3 at a temperature in a range from about 390° C. to about 450° C. for less than or equal to approximately 15 hours.
