摘要:
Provided is a Li2O—Al2O3—SiO2-based crystallized glass in which a yellowish tint due to TiO2, Fe2O3 or so on is reduced. The Li2O—Al2O3—SiO2-based crystallized glass contains, in terms of % by mass, 40 to 90% SiO2, 5 to 30% Al2O3, 1 to 10% Li2O, 0 to 20% SnO2, 1 to 20% ZrO2, 0 to 10% MgO, 0 to 10% P2O5, and 0 to below 2% TiO2.
