  • Glass composition for lamp, glass part for lamp, and process for producing lamp or glass composition for lamp
    Patent number: 8067322
    Abstract: A glass composition for lamps includes the following by weight percent: SiO2: 60-75 wt %; CeO2+Ce2O3: 0.01-5.2 wt %; SnO+SnO2: 0.01-5.2 wt %; Al2O3: 0.5-6 wt %; B2O3: 0-5 wt %; Li2O+Na2O+K2O: 13-20 wt %; MgO: 0.5-5 wt %; CaO: 1-10 wt %; SrO: 0-10 wt %; BaO: 0-10 wt %; ZnO: 0-10 wt %; Fe2O3+FeO: 0-0.2 wt %; and TiO2: 0-1 wt %. The glass composition for lamps that contains no lead or antimony achieves high ultraviolet screening capacity, ensuring fewer occurrences of initial coloring and ultraviolet ray caused coloring of glass.
    Type: Grant
    Filed: July 7, 2006
    Date of Patent: November 29, 2011
    Assignee: National Institute of Advanced Industrial Science and Technology
    Inventors: Ryousuke Sawa, Junko Abe, Tomoko Atagi, Masanobu Itou, Tomoko Akai, Masaru Yamashita

  • Glass Composition for Lamp and Lamp Manufactured From the Same
    Publication number: 20070254797
    Abstract: A glass composition for lamps includes: SiO2 (silicon dioxide) as a main component; Na2O (sodium oxide) in the range of 12 to 17 wt. %; MgO (magnesium oxide) in the range of 2.5 to 4 wt. %; and CaO (calcium oxide) in the rage of 5.3 to 7.3 wt. %, wherein the total content of MgO and CaO is in the range of 8 to 11 wt. %. Thereby, lamps can be manufactured at relatively low costs that exhibit superiority in fracture resistance, workability, erosion resistance with respect to the inner surface of a furnace, and suppressing the elution of alkali component.
