Abstract: A glass ceramic substrate made of a transparent, colored LAS glass ceramic is provided. The glass ceramic has a gradient layer with keatite solid solution and an underlying core with high-quartz solid solution as predominant crystal phase. The keatite solid solution in a depth of 10 μm or greater exceeds 50% of the sum of the high-quartz solid solution proportion and keatite solid solution proportion. The ceramization includes a crystal transformation step, in which the high-quartz solid solution is transformed at a maximum temperature in the range of 910° to 980° and a time period of between 1 and 25 minutes in part into the keatite solid solution.

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.
