ウインドウ製造用ガラス組成物
Document Type and Number:
Japanese Patent JP4607462
Kind Code:
B2
Abstract:
A glass composition of the soda-lime-silicate type is described which includes, by weight, the following coloring agents: 0.2-0.45% of Fe2O3 (total iron), 2-8 ppm of Se, 0-20 ppm of CoO, and 0-80 ppm of NiO. The coloring agents satisfy the relationship, 0.7<(200xNiO) +(5000xSe)+(6xFe3+)/(875xCoO)+(24xFe2+)<1.6 in which the NiO, Se, Fe3+, CoO and Fe2+contents are expressed in ppm, Fe3+and Fe2+are the content of ferric iron expressed in the form of Fe2O3 and FeO, respectively. The composition has a redox from 0.28 to 0.5, an overall light transmission under illuminant A (TLA) greater than 65% and a selectivity (SE) of greater than 1.25, when measured for a thickness of 3.85 mm. A window formed from at least one glass sheet produced from the aforementioned composition is also described.
