Abstract:
The present invention provides crystallized glass of three-dimensional shape for easily producing chemically strengthened glass of three-dimensional shape that resists damage and has exceptional transparency. This crystallized glass of three-dimensional shape: contains crystals; has light transmittance in terms of a thickness of 0.8 mm of 80% or higher; and contains 45-74% SiO2, 1-30% Al2O3, 1-25% Li2O, 0-10% Na2O, 0-5% K2O, a total of 0-15% of SnO2 and/or ZrO2, and 0-12% P2O5, these amounts expressing the oxide-based mass percentage.
