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.
Claims6
A glass ceramic comprising:
- a glass containing:
- SiO2 at a content of 20% by weight to 55% by weight;
- B2O3 at a 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, and
- a TiO2 content, a ZrO2 content, a SnO2 content, and a SrO content in the glass each being 0% by weight to 5% by weight;
- and
- aggregates including:
- 20% by weight to 50% by weight of a SiO2 aggregate,
- 1% by weight to 10% by weight of a TiO2 aggregate,
- 3% by weight or less of a ZrO2 aggregate, and
- 1% by weight or less of a ZnO aggregate,
- each relative to a weight of the glass ceramic.
