    摘要: A glass ceramic that contains a glass containing Si, B, Al, and Zn and aggregates. The glass has a SiO2 content of 20% by weight to 55% by weight, a B2O3 content of 15% by weight to 30% by weight, Al2O3, and ZnO, wherein a weight ratio of the SiO2 to the B2O3 (SiO2/B2O3) is 1.21 or higher, and a weight ratio of the Al2O3 to the ZnO (Al2O3/ZnO) is 0.8 to 1.3. A TiO2 content, a ZrO2 content, a SnO2 content, and a Sr0 content in the glass each are 0% by weight to 5% by weight. The aggregates include 20% by weight to 50% by weight of SiO2, 1% by weight to 10% by weight of TiO2, 3% by weight or less of ZrO2, and 1% by weight or less of ZnO each relative to the weight of the glass ceramic.

    摘要: A cover glass of the present invention is characterized by including in a glass composition at least three or more components selected from SiO2, Al2O3, B2O3, Li2O, Na2O, K2O, MgO, CaO, BaO, TiC2, Y2O3, ZrO2, and P2O5, and having an X value of 7, 400 or more calculated by the following equation. The X value is a value calculated by the equation X=61.1×[SiO2]+174.3×[Al2O3]+11.3×[B2O3]+124.7×[Li2O]−5.2×[Na2O]+226.7×[K2O]+139.4×[MgO]+117.5×[CaO]+89.6×[BaO]+191.8×[TiO2]+226.7×[Y2O3]+157.9×[ZrO2]−42.2×[P2O5].
