Abstract
Provided is a glass containing a crystalline phase, the glass including at least one crystalline phase selected from the group consisting of cristobalite, lithium disilicate, and petalite, in which a value of E/ρ, which is a ratio of Young's modulus E to specific gravity ρ, is 35 or more, and a glass transition point is 680° C. or higher.
Claims10
A glass containing a crystalline phase, comprising:
- crystalline phases including cristobalite and lithium disilicate;
- wherein the glass comprises, in mass % in terms of oxides, a ZrO2 component at a content of 2.0% or more;
- wherein, in mass % in terms of oxides,
- [(content of SiO2 component+content of Li20 component)/content of Al2O3 component] is 22.94 or more;
- wherein a value of E/ρ, which is a ratio of Young's modulus E to specific gravity ρ, is 35 or more, and
- a glass transition point is 680° C. or higher.
