ULTRAVIOLET 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% SiO 2 ; 0 to 1% B 2 O 3 ; exceeded 0% but not more than 20% Al 2 O 3 ; 0 to 10% Li 2 O; 5 to 20% Na 2 O; 0 to 15% K 2 O; 0 to 10% MgO; 0 to 10% CaO; 0 to 15% SrO; 0 to 2% refining agent; 2 to 20 ppm T-Fe 2 O 3 (in which T-Fe 2 O 3 denotes a total iron oxide content obtained by converting all of iron compounds into Fe 2 O 3 ); and 0 to 200 ppm TiO 2 . 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.
