Beschreibung
Zusammenfassung:	본 발명의 유리 조성물은 mol%로 나타내어, SiO66~72%, AlO1~4%, MgO 8~15%, CaO 1~8%, NaO 12~16%, KO 0~1%를 포함하고, MgO+CaO가 12~17%의 범위에 있으며, 몰비 CaO/(MgO+CaO)가 0.1~0.4의 범위에 있는 것을 특징으로 한다. 본 발명의 유리 조성물은, 플로트법에 의한 제조에 적합하며, 화학 강화에 적합하다. A glass composition of the present invention includes, in mol %, 66 to 72% SiO2, 1 to 4% Al2O3, 8 to 15% MgO, 1 to 8% CaO, 12 to 16% Na2O, and 0 to 1% K2O. A total content of MgO and CaO is in a range of 12 to 17%, and a molar ratio of CaO to the total content of MgO and CaO is in a range of 0.1 to 0.4. The glass composition of the present invention is suitable for production by the float process, and is suitable for chemical strengthening.
