Abstract:
Provided is a high-strength crystallized glass or substrate having a high visible light transmittance and a good color balance, which is suitable for use in protecting members of portable electronic devices, optical devices and the like. Provided is a crystallized glass comprising, in terms of mol % on an oxide basis: an SiO 2  component of 30.0% or more and 70.0% or less, an Al 2 O 3  component of 8.0% or more and 25.0%, an Na 2 O component of 0% or more and 25.0% or less, an MgO component of 0% or more and 25.0% or less, a ZnO component of 0% or more and 30.0% or less and a TiO 2  component of 0% or more and 10.0% or less, the molar ratio [Al 2 O 3 /(MgO+ZnO)] having a value of 0.5 or more and 2.0 or less, and comprising one or more selected from RAl 2 O 4 , RTi 2 O 5 , R 2 TiO 4 , R 2 SiO 4 , RAl 2 Si 2 O 8  and R 2 Al 4 Si 5 O 18  as a crystal phase.

Claim (Index 13):
The crystallized glass according to  claim 1 , wherein the glass comprises one or more selected from RAl 2 O 4 , R 2 Al 4 Si 5 O 18  and MgTi 2 O 4  as a crystal phase, provided that R is one or more selected from Zn, Mg and Fe.
