Abstract: A cover substrate for an electronic device including greater than or equal to 1% by weight post-consumer recycled cover substrate. A method of forming the cover substrate including the steps of (i) determining the composition of the post-consumer recycled cover substrate, (ii) determining the maximum amount of the post-consumer recycled cover substrate that can be added to a predetermined batch without causing the resulting cover substrate to fall out of specification, and (iii) forming the cover substrate from the combined recycled post-consumer cover substrate and the predetermined batch. Additionally, a method that includes steps of (i) determining the composition of the post-consumer recycled cover substrate, (ii) determining a target weight percentage of the post-consumer recycled cover substrate in a cover substrate, and (iii) determining weight percentages of other oxides to be added to the target weight percentage for the resulting combination to produce the cover substrate with a desired composition.

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.

CPC classification number: C03B32/02
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.
