Abstract: A method of strengthening an alkali aluminoborosilicate glass. A compressive layer extending from a surface of the glass to a depth of layer is formed by exchanging larger metal cations for smaller metal cations present in the glass. In a second step, metal cations in the glass are exchanged for larger metal cations to a second depth in the glass that is less than the depth of layer and increase the compressive stress of the compressive layer. Formation of the compressive layer and replacement of cations with larger cations can be achieved by a two-step ion exchange process. An alkali aluminoborosilicate glass having a compressive layer and a crack indentation threshold of at least 3000 gf is also provided.

Abstract: Disclosed herein are glass-ceramics having crystalline phases including β-spodumene ss and either (i) pseudobrookite or (ii) vanadium or vanadium containing compounds so as to be colored and opaque glass-ceramics having coordinates, determined from total reflectance—specular included—measurements, in the CIELAB color space of the following ranges: L*=from about 20 to about 45; a*=from about −2 to about +2; and b*=from about −12 to about +1. Such CIELAB color space coordinates can be substantially uniform throughout the glass-ceramics. In each of the proceeding, β-quartz ss can be substantially absent from the crystalline phases. If present, β-quartz ss can be less than about 20 wt % or, alternatively, less than about 15 wt % of the crystalline phases. Also Further crystalline phases might include spinel ss (e.g., hercynite and/or gahnite-hercynite ss), rutile, magnesium zinc phosphate, or spinel ss (e.g., hercynite and/or gahnite-hercynite ss) and rutile.

Abstract: Ion exchangeable glasses containing SiO2, Al2O3, Na2O, MgO, B2O3, and P2O5 are 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.

Abstract: A scratch resistant alkali aluminoborosilicate glass. The glass is chemically strengthened and has a surface layer that is rich in silica with respect to the remainder of the glass article. The chemically strengthened glass is then treated with an aqueous solution of a mineral acid other than hydrofluoric acid, such as, for example, HCl, HNO3, H2SO4, or the like, to selective leach elements from the glass and leave behind a silica-rich surface layer. The silica-rich surface layer improves the Knoop scratch threshold of the ion exchanged glass compared to ion exchanged glass that are not treated with the acid solution as well as the post-scratch retained strength of the glass.
