Crystallized glass housing |
摘要 |
To provide a crystallized glass housing excellent in properties suitable for a housing for an electronic device, such as shielding properties, high strength and production cost. A crystallized glass housing made of crystallized glass, said crystallized glass having a diffused transmittance of 15% or less in the entire light wavelength region of from 380 nm to 780 nm, as measured by using an integrated sphere. |

1. A crystallized glass housing made of crystallized glass, which is to accommodate an electronic device, said crystallized glass having a diffused transmittance of 15% or less in the entire light wavelength region of from 380 nm to 780 nm, as measured by using an integrated sphere, wherein the crystallized glass is white in appearance, and when reflected light of a C light source to the crystallized glass formed into a flat plate having a thickness of 2 mm is measured, the reflected light is within a range of an area surrounded by a straight line passing through a point A (x: 0.2500, y: 0.2500) and a point B (x: 0.4000, y: 0.3500), a straight line passing through the point B (x: 0.4000, y: 0.3500) and a point C (x: 0.4000, y: 0.4000), a straight line passing through the point C (x: 0.4000, y: 0. 4000) and a point D (x: 0.2500, y: 0.3000), and a straight line passing through the point D (x: 0.2500, y: 0.3000) and the point A (x: 0.2500, y: 0.2500) in CIE chromaticity coordinates. |
