Abstract:
A lithium-aluminosilicate glass or a corresponding glass ceramic that has a content of 0-0.4SnO2, 1.3-2.7% by weight of ΣSnO2+TiO2, 1.3-2.5% by weight of ZrO2, 3.65-4.3% by weight of ΣZrO2+0.87 (TiO2+SnO2), ≦0.04% by weight of Fe2O3, 50-4000 ppm of Nd2O3 and 0-50 ppm of CoO is described. The glass or the glass ceramic is color-neutral, has a turbidity of less than 1% HAZE and a high light transmission. The glazing time for conversion of the glass into glass ceramic is especially short with less than 2.5 hours.
