  • Glass with low solar transmittance
    Patent number: 8785338
    Abstract: Disclosed is a glass with low solar transmittance, which is characterized by that it has a basic composition of soda-lime-silica glass, that it contains as coloring components 0.70-1.70 mass % of Fe2O3 (total iron in terms of ferric iron), 0.15-0.45 mass % of FeO (ferrous iron), 0-0.8 mass % of TiO2, 100-350 ppm of CoO, 0-60 ppm of Se, 100-700 ppm of Cr2O3, and 3-150 ppm of MnO, that it has a ratio (Fe2+/Fe3+) of ferrous iron to ferric iron of 0.20-0.80. This glass has superior ultraviolet absorbing performance and infrared absorbing performance (heat insulation performance) and an appropriate transparency.
    Type: Grant
    Filed: July 10, 2012
    Date of Patent: July 22, 2014
    Assignee: Central Glass Company, Limited
    Inventors: Tatsuya Tsuzuki, Takahiro Mori, Naoko Yoshimura, Kota Yoshimura, Marin Yoshimura, Karen Yoshimura
