The nucleating agent is selected from the group consisting of ZrO2, TiO2, SnO2, HfO2, Ta2O5, Nb2O5, Y2O3, and combinations thereof. The nucleating agent may comprise greater than or equal to 50% ZrO2 and less than 50% of at least one compound selected from the group consisting of TiO2, SnO2, HfO2, Ta2O5, Nb2O5, Y2O3, and combinations thereof. The glass-ceramic article may have a molar ratio of MgO to Li2O of greater than or equal to 1:1. The glass-ceramic article may satisfy the relationship 0.85≤(MgO (mol %)+Li2O (mol %))/Al2O3 (mol %)≤1.2. The glass-ceramic article may comprise a crystalline phase comprising hexagonal stuffed β-quartz and glass.

Abstract: A glass substrate formed from a glass composition is disclosed. In embodiments, the composition comprises: from 60 mol. % to 75 mol. % SiO2; from 2 mol. % to 15 mol. % Li2O; from 1.9 mol. % to 15 mol. % Y2O3; and at least one of B2O3 and Na2O. B2O3+Na2O is from 2 mol. % to 13 mol. %. Y2O3+Al2O3 is from 10 mol. % to 24 mol. %. A ratio R2O/Al2O3 is from 0.5 to 4, where R2O is a total concentration of Li2O, Na2O, K2O, Rb2O, and Cs2O. (R2O+RO)/Al2O3 is from 0.5 to 4.5, where RO is a total concentration of BeO, MgO, CaO, SrO, and BaO. The glass substrate has a Young's modulus from 75 gigapascals (GPa) to 110 GPa. The glass substrate is ion exchangeable to form a strengthened glass article.

IPC: C03C17/34
Abstract: A glass-based assembly includes a glass or glass-ceramic substrate comprising a surface. The surface has flaws, such as a population of small cracks extending into the surface, whereby the substrate is weakened relative to ideal strength thereof. The assembly further includes a coating coupled to the substrate and overlaying at least some of the flaws. Ultimate strength of the substrate with the coating coupled thereto is greater than that of the substrate alone, without the coating.

Abstract: Embodiments of thermally and chemically strengthened glass-based articles are disclosed. In one or more embodiments, the glass-based articles may include a first surface and a second surface opposing the first surface defining a thickness (t), a first CS region comprising a concentration of a metal oxide that is both non-zero and varies along a portion of the thickness, and a second CS region being substantially free of the metal oxide of the first CS region, the second CS region extending from the first surface to a depth of compression of about 0.17·t or greater. In one or more embodiments, the first surface is flat to 100 μm total indicator run-out (TIR) along any 50 mm or less profile of the first surface. Methods of strengthening glass sheets are also disclosed, along with consumer electronic products, laminates and vehicles including the same are also disclosed.
