Abstract

A glass ceramic that contains a glass containing Si, B, Al, and Zn and aggregates. The glass has a SiOcontent of 20% by weight to 55% by weight, a BOcontent of 15% by weight to 30% by weight, AlO, and ZnO, wherein a weight ratio of the SiOto the BO(SiO/BO) is 1.21 or higher, and a weight ratio of the AlOto the ZnO (AlO/ZnO) is 0.8 to 1.3. A TiOcontent, a ZrOcontent, a SnOcontent, 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 SiO, 1% by weight to 10% by weight of TiO, 3% by weight or less of ZrO, and 1% by weight or less of ZnO each relative to the weight of the glass ceramic.
