ION EXCHANGEABLE GLASS CONTAINING BORON AND PHOSPHOROUS |
摘要 |
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. |
