Abstract: Ion exchangeable glasses containing SiO2, Na2O, MgO, and, optionally, at least one of Li2O and ZrO2. These glasses are also free of at least one of B2O3, K2O, CaO, and P2O5. These glasses may be ion-exchanged to achieve a depth of compressive layer of at least about 40 μm or up to about 50 μm and a maximum surface compressive stress of at least about 950 MPa, in some embodiments, at least 1000 MPa and, in other embodiments, at least about 1100 MPa. The ion-exchanged glasses, when subsequently heat-treated, have a retained compressive stress of at least about 600 MPa at the surface of the glass and, in some embodiments, at least about 750 MPa. The glasses also exhibit high levels of durability when exposed to strong acid.

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.
