摘要:
A lithium-aluminosilicate glass or a corresponding glass ceramic that has a content of 0-0.4 SnO2, 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.

摘要:
A transparent, colorless lithium-aluminosilicate glass ceramic plate with high-quartz mixed crystals as the prevailing crystal phase, which is provided on one side with an opaque, colored, temperature-stable coating over the entire surface or over the entire surface to a large extent, is described, which has a content of Nd2O3 of 40 to 4000 ppm, a Yellowness Index of less than 10% with a 4 mm glass (ceramic) layer thickness, and a variegation of colors of the glass or the glass ceramic in the CIELAB color system of C* of less than 5. The glass ceramic plate preferably has a composition (in % by weight based on oxide) of: Li2O 3.0-4.5, Na2O 0-1.5, K2O 0-1.5, ΣNa2O+K2O 0.2-2.0, MgO 0-2.0, CaO 0-1.5, SrO 0-1.5, BaO 0-2.5, ZnO 0-2.5, B2O3 0-1.0, Al2O3 19-25, SiO2 55-69, TiO2 1-3, ZrO2 1-2.5, SnO2 0-0.4, ΣSnO2+TiO2
