PROBLEM TO BE SOLVED: To provide LiO-AlO-SiO-based crystallized glass using SnOas an alternative clarifier for AsOand SbO, capable of suppressing yellow coloration due to FeOor TiO, and having excellent transparent feeling, and also to provide white LiO-AlO-SiO-based crystallized glass easier to achieve low thermal expansion characteristics and low dielectric loss characteristics.SOLUTION: LiO-AlO-SiO-based crystallized glass includes, by mass% as a composition, 55-75% SiO, 20.5-27% AlO, 2% or more LiO, 1.5-3% TiO, 3.8-5% TiO+ZrO, and 0.1-0.5% SnO, and satisfies th relations 3.7≤LiO+0.741MgO+0.367ZnO≤4.5, and SrO+1.847CaO≤0.5.SELECTED DRAWING: None |
