摘要 |
Embodiments of glass composition including at least about 65 mol % SiO2, Al2O3 in the range from about 7 mol % to about 11 mol %, Na2O in the range from about 13 mol % to about 16 mol %; and a non-zero amount of one or more alkali earth metal oxides selected from MgO, CaO and ZnO, wherein the sum of the alkali earth metal oxides is up to about 6 mol %, are disclosed. The glass compositions can be processed using fusion forming processes and float forming processes and are ion exchangeable. Glass articles including such glass compositions and methods of forming such glass articles are also disclosed. The glass articles of one or more embodiments exhibit a Vickers indentation crack initiation load of at least 8 kgf. |
