GLASS AND GLASS SUBSTRATE |
| 摘要 |
Devised are a glass and glass substrate, which contain an alkaline component at a low content, are low in density and thermal expansion coefficient, are high in strain point and Young's modulus, and are excellent in devitrification resistance, meltability, formability, and the like. That is, the glass of the present invention includes as a glass composition, in terms of mass %, 58 to 70% of SiO2, 16 to 25% of Al2O3, 3 to 8% of B2O3, 0 to 5% of MgO, 3 to 13% of CaO, 0 to 6% of SrO, 0 to 6% of BaO, 0 to 5% of ZnO, 0 to 5% of ZrO2, 0 to 5% of TiO2, and 0 to 5% of P2O5. |
