Abstract: Crystallizable glasses, glass-ceramics, IXable glass-ceramics, and IX glass-ceramics are disclosed. The glass-ceramics exhibit ?-spodumene ss as the predominant crystalline phase. These glasses and glass-ceramics, in mole %, include: 60-75 SiO2; 10-18 Al2O3; 5-14 Li2O; and 4.5 B2O3. The glass-ceramics also have a Vickers initiation crack threshold of at least about 25 kgf.

Abstract: According to one embodiment, a glass article may include SiO2, Al2O3, Li2O and Na2O. The glass article may have a softening point less than or equal to about 810° C. The glass article may also have a high temperature CTE less than or equal to about 27×10?6/° 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 ?m after ion exchange in a salt bath comprising KNO3 at a temperature in a range from about 390° C. to about 450° C. for less than or equal to approximately 15 hours.

Abstract: Methods are disclosed for producing chemically-strengthened, borosilicate, glass articles. The articles are produced from batch components which are selected, at least in part, based on measured and/or estimated values for the coordination state of B2O3 in the glass. In this way, such chemical-strengthening properties as mutual diffusivity, maximum surface compressive stress, and/or indentation threshold can be improved.

Abstract: Ion exchangeable glass articles are disclosed. In one embodiment, a glass article formed from alkali aluminosilicate glass which may include Ga2O3, Al2O3, Na2O, SiO2, B2O3, P2O5 and various combinations thereof. The glass article may generally include about X mol % of Ga2O3 and about Z mol % of Al2O3, wherein 0?X?20, 0?Z?25 and 10?(X+Z)?25. The glass article may also include from about 5 mol % to about 35 mol % Na2O, SiO2 may be present in an amount from about 40 mol % to about 70 mol % SiO2. The glass article may further include Y mol % B2O3 where Y is from 0 to about 10. The glass article may further include (10-Y) mol % of P2O5. Glass articles formed according to the present invention may be ion-exchange strengthened. In addition, the glass articles may have a low liquid CTE which enables the glass articles to be readily formed into complex shapes.
