Ultraviolet Ray Transmitting Glass Composition and Glass Article Making Use of the Same |
摘要 |
An ultraviolet ray transmitting glass composition including the following components, in terms of mass % or mass ppm: 60 to 79% SiO2; 0 to 1% B2O3; exceeded 0% but not more than 20% Al2O3; 0 to 10% Li2O; 5 to 20% Na2O; 0 to 15% K2O; 0 to 10% MgO; 0 to 10% CaO; 0 to 15% SrO; 0 to 2% refining agent; 2 to 20 ppm T-Fe2O3 (in which T-Fe2O3 denotes a total iron oxide content obtained by converting all of iron compounds into Fe2O3); and 0 to 200 ppm TiO2. The ultraviolet ray transmitting glass composition is suitable for a glass article, such as a bioanalytical device that is used for analysis using ultraviolet rays.
