| 简介 |
A glass article including at least about 40 mol % SiO2 and, optionally, a colorant imparting a preselected color is disclosed. In general, the glass includes, in mol %, from about 40-70 SiO2, 0-25 Al2O3, 0-10 B2O3; 5-35 Na2O, 0-2.5 K2O, 0-8.5 MgO, 0-2 ZnO, 0-10% P2O5 and 0-1.5 CaO. As a result of ion exchange, the glass includes a compressive stress (σs) at at least one surface and, optionally, a color. In one method, communicating a colored glass with an ion exchange bath imparts σs while in another; communicating imparts σs and 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. |
