Zircon compatible, ion exchangeable glass with high damage resistance |
| 摘要 |
An ion exchangeable glass having a high degree of resistance to damage caused by abrasion, scratching, indentation, and the like. The glass comprises alumina, B2O3, and alkali metal oxides, and contains boron cations having three-fold coordination. The glass, when ion exchanged, has a Vickers crack initiation threshold of at least 10 kilogram force (kgf). |

1. A glass, the glass comprising:
66-74 mol % SiO2; at least about 10 mol % R2O, wherein R2O comprises 9-20 mol % Na2O; 9-22 mol % Al2O3, wherein Al2O3(mol %)<R2O(mol %); and B2O3, wherein B2O3(mol %)−(R2O(mol %)−Al2O3(mol %))≧3 mol %, and wherein the glass is ion exchangeable. |
