Optical colored and filter glass |
| abstract |
Low alkali, high phosphate and high Al2O3 content glasses are described which are highly suitable for optical colored and filter glasses. They exhibit a glass transformation temperature Tg>450 DEG C. and have the following composition, in percent by weight: -P2O5 71.0-76.0 -SiO2 0.25-2.5 -B2O3 2.4-3.75 -Al2O3 8.6-11.6 -R2O (alkali oxide) 1.25-6.5 -CaO 0.5-1.65 -MgO 2.0-3.5 -Refining Agent 0.2-0.6 -CeO2 0.1-0.4 -F' 0.2-0.4 and -CuO 1.0-10.0. - |
