Abstract:
A transparent low-colour lithium aluminium silicate (LAS) glass ceramic and the use thereof are provided. The ceramic has an environmentally friendly composition with high-quartz mixed crystals as the main crystal phase. The glass ceramic contains the following components (in wt % on the basis of oxide): TiO2 1.6- CaO+SrO +BaO. In some embodiments, the glass ceramic has a hue c* of less than 5.5, a light transmission Y greater than 81% and has no visually disruptive diffusion.
