High transmittance glass sheet and method of manufacture the same |
摘要 |
The present invention is to provide a high transmittance glass sheet that has a composition containing as coloring components, expressed in wt. %, 0.005 to less than 0.02% of total iron oxide in terms of Fe2O3, less than 0.008% of FeO, and 0 to 0.25% of cerium oxide and having a ratio of FeO in terms of Fe2O3 to the total iron oxide of lower than 40%, and exhibits high visible light transmittance and solar radiation transmittance. Alternatively, a high transmittance glass sheet is provided that contains not more than 0.06% of total iron oxide and 0.025 to 0.20% of cerium oxide and has a ratio of a fluorescence intensity at 395 nm to a fluorescence intensity at 600 nm of 10% or higher when subjected to ultraviolet irradiation at a wavelength of 335 nm. <IMAGE> |
