Abstract
In an amorphous glass, an SiOcontent is in a range of 56 mol % or more. An MgO content is in a range of 15 mol % or more and 28 mol % or less. An LiO content is in a range of 0.2 mol % or more. An NaO content is in a range of 5 mol % or less. A total content of AlO, MgO, and CaO (AlO+MgO+CaO) is 36.50 mol % or less. The total content of SiO, MgO, LiO, AlO, and CaO (SiO+MgO+LiO+AlO+CaO) is 97.5 mol % or more. A mole ratio of the total content of SiOand MgO relative to the LiO content [(SiO+MgO)/LiO] is 13 or more. A mole ratio of a CaO content relative to a total content of AlOand MgO [CaO/(AlO+MgO)] is 0.10 or less.
