Disclosed herein are glass compositions, articles made from the disclosed glass compositions, and methods of making the same. More specifically, disclosed herein is a glass composition comprising from about 10 to about 14 mol % of KO; from 0 to about 4 mol % of CaO; from about 14 to about 18 mol % of AlO; and from about 66 to about 74 mol % SiO.

Glass compositions, glass articles, and methods of making the same

A glass article including at least about 40 mol % SiOand, optionally, a colorant imparting a preselected color is disclosed. In general, the glass includes, in mol %, from about 40-70 SiO, 0-25 AlO, 0-10 BO; 5-35 NaO, 0-2.5 KO, 0-8.5 MgO, 0-2 ZnO, 0-10% POand 0-1.5 CaO. As a result of ion exchange, the glass includes a compressive stress (σ) at at least one surface and, optionally, a color. In one method, communicating a colored glass with an ion exchange bath imparts σwhile in another; communicating imparts σand a preselected color. In the former, a colorant is part of the glass batch while in the latter; it is part of the bath. In each, the colorant includes one or more metal containing dopants formulated to impart to a preselected color. Examples of one or more metal containing dopants include one or more transition and/or rare earth metals.

Colored alkali aluminosilicate glass articles

An ion exchangeable glass having a high degree of resistance to damage caused by abrasion, scratching, indentation, and the like. The glass comprises alumina, BO, and alkali metal oxides, and contains boron cations having three-fold coordination. The glass, when ion exchanged, has a Vickers crack initiation threshold of at least 10 kilogram force (kgf).

Zircon compatible, ion exchangeable glass with high damage resistance

An aluminoborosilicate glass includes alkaline earth oxides and is substantially free of alkali oxides. The glass may be fusion formable and may be useful as a substrate or other article, such as with consumer and commercial electronic devices.

Aluminoborosilicate glass substantially free of alkali oxides

Methods of making a bioactive glass fiber include forming a melt of a glass composition including: 50 to 70% SiO; 0.1 to 10% AlO, 5 to 30% NaO, 0.1 to 15% KO, 0.1 to 15% MgO, 0.1 to 20% CaO, and 5 to 10% PO, based on a 100 wt % of the glass composition. The melt has a viscosity of from 200 Poise to 2,000 Poise. Methods include drawing the melt into a drawn glass fiber. Bioactive glass compositions include: 60 to 70% SiO; 15 to 30% NaO, 5 to 15% KO, 1 to 10% CaO, and 5 to 10% PO, based on a 100 wt % of the glass composition.

High liquidus viscosity bioactive glass

Glasses that can be chemically strengthened and are colored by transition metals. Most of the glasses are black, with some having high damage resistance and compressive surface layers having high compressive stress and depth of layer after ion exchange. These colored glasses do not require a post-forming heat treatment to produce color and are formable by fusions drawing, rolling, slot drawing, and float glass processes.

Transition metal-containing, ion exchangeable colored glasses

A bioactive glass-ceramic composition as defined herein. Also disclosed are methods of making and using the disclosed compositions.

Lithium disilicate glass-ceramic compositions and methods thereof

A glass article comprising an alkali aluminosilicate glass that is formable by down-draw processes for example slot- and fusion-draw to thicknesses of 125 &#x3bc;m or less and is capable of being chemically strengthened by ion-exchange to achieve a compressive stress at its surface of at least 950 MPa, in some embodiments at least about 1000 MPa, and in other embodiments at least about 1100 MPa. The high surface compressive stress allows the glass to retain net compression and thus contain surface flaws when the glass is subjected to bending around a tight radius. The glass may be used in foldable display applications.

Ion-exchangeable glass with high surface compressive stress

A glass composition comprises a germanosilicate glass containing 5-35 mol % ZnO. The glass composition has a relatively high refractive index, good glass-forming ability, and UV-shielding properties.
