Ion exchangeable glass with high crack initiation threshold |
| 摘要 |
Alkali aluminosilicate glasses that are resistant to damage due to sharp impact and capable of fast ion exchange are provided. The glasses comprise at least 4 mol % P2O5 and, when ion exchanged, have a Vickers indentation crack initiation load of at least about 7 kgf. |

1. An alkali aluminosilicate glass comprising at least about 4 mol % P2O5 and from 0 mol % to about 4 mol % B2O3, wherein the alkali aluminosilicate glass is lithium-free and ion exchanged to a depth of layer of at least about 10 μm, and wherein:
i. 1.3<[(P2O5+R2O)/M2O3]≦2.3; where M2O3=Al2O3+B2O3, and R2O is the sum of monovalent cation oxides present in the alkali aluminosilicate glass. |
