Lead- and barium-free crystal glass with high light transmission.

摘要

Lead- and barium-free crystal glass for the production of high-quality glasses and domestic articles having high light transmission, a refractive index nd of greater than 1.52, a density of at least 2.45 g/cm<3>, high hydrolytic resistance, good solarisation resistance, and a K2O + ZnO content of greater than 10 % by weight, where the glass system is built up from an alkali-lime-silicate glass containing TiO2, ZrO2, Nb2O3 and possibly Ta2O5, and/or combinations thereof.
