Abstract
(EN)
A Li2O-Al2O3-SiO2-based crystallized glass is provided. In this Li2O-Al2O3-SiO2-based crystallized glass, yellow coloration due to TiO2 and Fe2O3, etc., is suppressed. This Li2O-Al2O3-SiO2-based crystallized glass is characterized by containing, in mass%, 40-90% SiO2, 5-30% Al2O3, 1-10% Li2O, 0-20% SnO2, 1-20% ZrO2, 0-10% MgO, 0-10% P2O5, and 0% to less than 2% TiO2.
