Abstract
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 SrO 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.
