GLASS COMPOSITION SUITABLE FOR CHEMICAL STRENGTHENING AND CHEMICALLY STRENGTHENED GLASS ARTICLE
摘要：
Provided is a glass composition suitable for production using large-scale sheet glass mass production facilities by the float process or the like, having high heat resistance, and suitable for chemical strengthening. Specifically, provided is a glass composition containing, in mass %: 60 to 66% SiO2; 10 to 16% Al2O3; 0 to 1% B2O3; 3 to 10% MgO; 0 to 1% CaO; 1 to 9% SrO; O to 4% BaO; 0 to 2% ZnO; 0 to 1% Li2O; 10 to 20% Na2O; 0 to 5% K2O; O to 2% TiO2; 0 to 0.1% ZrO2; and 0 to 2% total iron oxide in terms of Fe2O3. In this glass composition, a total content of MgO, CaO, SrO, and BaO is in a range of 10 to 20%, a total content of Li2O, Na2O, and K2O is in a range of 14 to 20%, and a content of SrO is higher than a content of CaO.
摘要（中）：

本发明提供一种玻璃组合物，其适用于通过浮法等使用大规模平板玻璃批量生产设备，耐热性高，适于化学强化的玻璃组合物。 具体地，提供了以质量％计含有60〜66％的SiO 2的玻璃组合物。 10〜16％的Al2O3; 0至1％B2O3; 3〜10％MgO; 0〜1％CaO; 1〜9％SrO; O至4％BaO; 0〜2％ZnO; 0〜1％Li2O; 10〜20％Na2O; 0〜5％K2O; O至2％TiO 2; 0〜0.1％ZrO 2; 以Fe2O3计，氧化铁总量为0〜2％。 在该玻璃组合物中，MgO，CaO，SrO，BaO的总含量在10〜20％的范围内，Li 2 O，Na 2 O，K 2 O的总含量在14〜20％的范围内， 的SrO高于CaO含量。
