| 摘要 |
Lead- and barium-free crystal glass for the production of high-quality glasses and domestic articles, having high optical transmission, a refractive index nD of greater than 1.52, a density of at least 2.45 g/cm3, high hydrolytic resistance, good solarization resistance, and a K2O+ZnO content of greater than 10% by weight, the glass system being based on an alkali-lime-silicate glass containing TiO2, ZrO2, Nb2O3 and possibly Ta2O5 and/or combinations thereof.
