Patent number: 9440877Abstract: The present disclosure relates to fusion formable highly crystalline glass-ceramic articles whose composition lies within the SiO2—R2O3—Li2O/Na2O—TiO2 system and which contain a silicate crystalline phase comprised of lithium aluminosilicate (?-spodumene and/or ?-quartz solid solution) lithium metasilicate and/or lithium disilicate. Additionally, these silicate-crystal containing glass-ceramics can exhibit varying Na2O to Li2O molar ratio extending from the surface to the bulk of the glass article, particularly a decreasing Li2O concentration and an increasing Na2O concentration from surface to bulk. According to a second embodiment, disclosed herein is a method for forming a silicate crystalline phase-containing glass ceramic.Type: GrantFiled: October 23, 2014Date of Patent: September 13, 2016Assignee: Corning IncorporatedInventors: George Halsey Beall, Nicholas Francis Borrelli, Charlene Marie Smith, Steven Alvin Tietje

Publication number: 20160102011Abstract: Embodiments of a glass-based article including a first surface and a second surface opposing the first surface defining a thickness (t) of about 3 millimeters or less (e.g., about 1 millimeter or less), and a stress profile, wherein all points of the stress profile between a thickness range from about 0·t up to 0.3·t and from greater than 0.7·t, comprise a tangent that is less than about ?0.1 MPa/micrometers or greater than about 0.1 MPa/micrometers, are disclosed. In some embodiments, the glass-based article includes a non-zero metal oxide concentration that varies along at least a portion of the thickness (e.g., 0·t to about 0.3·t). In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a point between the first surface and the second surface and increases from the point to the second surface. The concentration of the metal oxide may be about 0.05 mol % or greater or about 0.5 mol % or greater throughout the thickness.Type: ApplicationFiled: October 8, 2015Publication date: April 14, 2016Inventors: Guangli Hu, Charlene Marie Smith, Zhongzhi Tang, Steven Alvin Tietje
