A group of glass compositions in the LiO—AlO—SiO—BOfamily that can be chemically strengthened in single or multiple ion exchange baths containing at least one of NaNOand KNOfor a short time (2-4 hours) to develop a deep depth of layer (DOL). In some instances, the DOL is at least 70 μm; in others, at least about 100 μm. The ion exchanged glasses have a high damage resistance (indentation fracture toughness ranging form greater than 10 kgf to greater than 50 kgf) that is better than or at least comparable to that of sodium aluminosilicate glasses.

Chemically strengthenable lithium aluminosilicate glasses with inherent damage resistance

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 about 0.7·t up to t, comprise a tangent with a slope having an absolute value greater than about 0.1 MPa/micrometer, 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) and a maximum central tension in the range from about 80 MPa to about 100 MPa. In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a value at a point between the first surface and the second surface and increases from the value 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. Methods for forming such glass-based articles are also disclosed.

Glass-based articles including a metal oxide concentration gradient

A laminate includes a first glass article having a first thickness, a first annealing point (T), and a first softening point (T), a second glass article having a second thickness, a second annealing point (T), and a second softening point (T), and an interlayer disposed between the first glass article and the second glass article. The first thickness is greater than the second thickness, the second annealing point (T) is less than or equal to the first annealing point (T), and the second softening point (T) is greater than the first softening point (T).

Uniformly pair sagged glass articles and hybrid laminates

Ion exchangeable glasses containing SiO, AlO, NaO, MgO, BO, and POare provided. The compressive stresses of these ion exchanged glasses are greater than 900 megapascals (MPa) at a depth of 45 or 50 microns (μm) with some glasses exhibiting a compressive stress of at least 1 gigaPascals (GPa). The ion exchange rates of these glasses are much faster than those of other alkali aluminosilicate glasses and the ion exchanged glass is resistant damage to impact damage. A method of ion exchanging the glass is also provided.

Ion exchangeable glass containing boron and phosphorous

A laminate includes a first glass article having a first thickness, a first annealing point, and a first softening point, a second glass article having a second thickness, a second annealing point, and a second softening point, and an interlayer disposed between the first glass article and the second glass article. The first thickness is greater than the second thickness, the second annealing point is less than or equal to the first annealing point, and the second softening point is greater than the first softening point.

According to one embodiment, a glass article may include SiO, AlO, LiO and NaO. The glass article may have a softening point less than or equal to about 810&#xb0; C. The glass article may also have a high temperature CTE less than or equal to about 27&#xd7;10/&#xb0; C. The glass article may also be ion exchangeable such that the glass has a compressive stress greater than or equal to about 600 MPa and a depth of layer greater than or equal to about 25 &#x3bc;m after ion exchange in a salt bath comprising KNOat a temperature in a range from about 390&#xb0; C. to about 450&#xb0; C. for less than or equal to approximately 15 hours.

The glass has a crack initiation threshold that is sufficient to withstand direct impact, has a retained strength following abrasion that is greater than soda lime and alkali aluminosilicate glasses, and is resistant to damage when scratched. The enclosure includes cover plates, windows, screens, and casings for mobile electronic devices and information terminal devices.

Crack and scratch resistant glass and enclosures made therefrom

A silicate glass that is tough and scratch resistant. The toughness is increased by minimizing the number of non-bridging oxygen atoms in the glass.
