Document Type and Number:
WIPO Patent Application WO/2021/221067
Kind Code:
A1
Abstract:
The present invention relates to a glass containing, in molar percentage with respect to oxide, 45-65% of SiO2, 18-30% of Al2O3, 7-15% of Li2O, 0-10% in total of at least one selected from among Y2O3 and La2O3, 0-10% of P2O5, 0-10% of B2O3, and 0-4% of ZrO2, wherein when the content of Al2O3 is [Al2O3], the content of P2O5 is [P2O5], the total content of alkali metal oxides is [R2O], and the total content of alkaline-earth metal oxides is [RO], [Al2O3]-[R2O]-[RO]-[P2O5]>0 is satisfied.
