摘要： Ion-exchanged glass ceramic articles described herein have a stress that decreases with increasing distance according to a substantially linear function from a depth of about 0.07 t to a depth of about 0.26 t from the outer surface of the ion-exchanged glass ceramic article from a compressive stress to a tensile stress. The stress transitions from the compressive stress to the tensile stress at a depth of from about 0.18 t to about 0.25 t from the outer surface of the ion-exchanged glass ceramic article. An absolute value of a maximum compressive stress at the outer surface of the ion-exchanged glass article is from 1.8 to 2.2 times an absolute value of a maximum central tension (CT) of the ion-exchanged glass article, and the glass ceramic article has a fracture toughness of 1 MPa√m or more as measured according to the double cantilever beam method.

摘要： Methods of manufacturing a glass-based article comprise: after mechanical polishing of a glass-based substrate, treating at least one surface of the glass-based substrate for protection of the at least one surface from contamination and/or for removal of contaminants from the at least one surface by a treatment other than ultrasonic cleaning; and exposing the glass-based substrate to an ion exchange treatment after the treating step to form the glass-based article. The treating step includes: exposing the at least one surface to a high pH soaking for removal of contaminants; deionizing the at least one surface for removal of contaminants; and/or applying a temporary coating to the at least one surface for protection of the at least one surface from contamination, and removing the temporary coating prior to the ion exchange treatment step. The ion exchange treatment may comprise a molten salt bath having an increased pH and temperature.

摘要： Glass and glass ceramic compositions having a combination of lithium disilicate and -spodumene crystalline phases along with methods of making the glass and glass ceramic compositions are described. The compositions are compatible with conventional rolling and float processes and have high mechanical strength and fracture resistance. Further, the compositions are able to be chemically tempered to even higher strength glass ceramics that are useful as large substrates in multiple applications.

摘要： Provided are methods of forming a chemically strengthened glass-based article. Certain methods comprise: providing a glass-based substrate comprising a first surface and a second surface opposing the first surface defining a thickness ( t ), a length dimension, a width, and a weight; and ion exchanging a plurality of alkali ions into the glass-based substrate to form a non-zero alkali metal oxide concentration that varies along at least a substantial portion of the thickness ( t ). The ion exchanging comprises immersing a glass-based substrate in a molten salt bath comprising at least about 90% by weight KNO 3 , and less than about 10% by weight NaNO 3 for a time in the range of 70% to 130% of the ion exchange time that produces a peak central tension (CT) with the same molten salt bath composition and temperature. Also provided are ion exchanged glass-based articles prepared by said methods.
