    Abstract: The embodiments described herein relate to chemically and mechanically durable glass compositions and glass articles formed from the same. In another embodiment, a glass composition may include from about 70 mol. % to about 80 mol. % SiO2; from about 3 mol. % to about 13 mol. % alkaline earth oxide; X mol. % Al2O3; and Y mol. % alkali oxide. The alkali oxide may include Na2O in an amount greater than about 8 mol. %. A ratio of Y:X may be greater than 1 and the glass composition may be free of boron and compounds of boron. In some embodiments, the glass composition may also be free of phosphorous and compounds of phosphorous. Glass articles formed from the glass composition may have at least a class S3 acid resistance according to DIN 12116, at least a class A2 base resistance according to ISO 695, and a type HGA1 hydrolytic resistance according to ISO 720.

    Abstract translation: 本文所述的实施方案涉及由其形成的化学和机械耐久的玻璃组合物和玻璃制品。 在另一个实施方案中,玻璃组合物可以包含约70mol。 %至约80mol。 %SiO2; 约3mol。 %至约13mol。 %碱土金属氧化物; X mol。 %Al2O3; 和Y mol。 %碱金属氧化物。 碱金属氧化物可以包括大于约8mol的量的Na 2 O。 %。 Y:X的比例可以大于1,玻璃组合物可以不含硼和硼化合物。 在一些实施方案中,玻璃组合物还可以不含磷和磷的化合物。 由玻璃组合物形成的玻璃制品可以具有根据DIN 12116的至少S3级耐酸性,至少根据ISO 695的A2级耐碱性和根据ISO 720的HGA1型耐水解性。
