Vanadium containing soda-lime-glass

Abstract

Abstract The invention relates to a vanadium-containing soda-lime glass, in particular glass which can be processed by the float method and has increased UV absorption for wavelengths below 350nm, characterised in that it contains from 70 to 74% by weight of SiO2, from 0.00 to 2.0% by weight of Al2O3, less than about 0.1% by weight of Fe2O3, from 0.00 to 0.15% by weight of TiO2, from 7.5 to 10.0% by weight of CaO, from 3.5 to 5.4% by weight of MgO, from 12.0 to 15.0% by weight of Na2O, from 0.0 to 1.0% by weight of K2O, from 0 to 0.02% by weight of BaO, from 0.1 to 0.3% by weight of SO3, from 3 to 7 ppm by weight of CoO and from 0.10 to 0.3% by weight of V2O5, the sum of all the percentages by weight always being 100, and to the use thereof for single and multiple glazing, in particular glazing having UV-sensitive layers of organic and/or inorganic polymers, or containing UV-sensitive adhesive compositions. <IMAGE>
