Abstract: A glass-ceramic article comprises: a center-volume composition comprising (on an oxide basis): 55-75 mol % SiO2; 0.2-10 mol % Al2O3; 0-5 mol % B2O3; 15-30 mol % Li2O; 0-2 mol % Na2O; 0-2 mol % K2O; 0-5 mol % MgO; 0-2 mol % ZnO; 0.2-3.0 mol % P2O5; 0.1-10 mol % ZrO2; 0-4 mol % TiO2; and 0-1.0 mol % SnO2. Lithium disilicate and either β-spodumene or β-quartz are the two predominant crystalline phases (by weight) of the glass-ceramic article. The glass-ceramic article further comprises tetragonal ZrO2 as a crystalline phase. The composition of the glass-ceramic article from a primary surface into a thickness of the glass-ceramic article can comprise over 10 mol % Na2O (on an oxide basis), with the mole percentage of Na2O decreasing from the primary surface towards the center-volume. The glass-ceramic article exhibits a ring-on-ring load-to-failure of at least 120 kgf, when the thickness of the glass-ceramic article is 0.3 mm to 2.0 mm.

Abstract: A method for ceramming a glass article to a glass-ceramic includes placing a glass article into a heating apparatus, and heating the glass article to a first hold temperature at a first predetermined heating rate. The glass article is held at the first hold temperature for a first predetermined duration. The viscosity of the glass article is maintained within log viscosity ±1.0 poise during the first predetermined duration. The glass article is then heated from the first hold temperature to a second hold temperature at a second predetermined heating rate. The glass article is held at the second hold temperature for a second duration. A density of the glass article is monitored from the heating of the glass article from the first hold temperature through the second duration, and the second duration is ended when an absolute value of a density rate of change of the glass article is less than or equal to 0.10 (g/cm3)/min.

Abstract: A textured article is described herein that may include a glass-based substrate comprising a first major surface and a second major surface. The first major surface may be opposite the second major surface. At least a portion of the first major surface may be textured. The portion of the first major surface that is textured may have a roughness Ra of greater than or equal to 400 nm and an average pitch. A ratio of roughness Ra to average pitch may be from about 0.01 to about 0.04. At least a portion of the textured article may have an opacity of greater than about 70% or may have a coefficient of friction of from about 0.25 to about 0.4. The coefficient of friction may be measured as the kinetic coefficient of friction using a 500 g load on a foam rubber according to ASTM D1984.

Abstract: A method for forming glass ceramic articles includes heating a stack of glass sheets to a nucleation temperature to create a nucleated crystallizable stack of sheets; heating the nucleated crystallizable stack of glass sheets to a crystallization temperature; and maintaining the crystallization temperature for a predetermined period of time to produce the glass-ceramic articles. The stack of glass sheets has a mass index of less than or equal to 35.
