Abstract: A lithium-containing, transparent glass-ceramic material is provided. The material has low thermal expansion and has an amorphous, lithium-depleted, vitreous surface zone. The zone is at least 50 nm thick on all sides and encloses a crystalline interior, which has high transmission. The material includes a transition region connecting the zone and the interior.

Abstract: A formulation usable to produce plates and shaped bodies has a base slip, quartz glass particles and multicomponent glass particles that are crystallizable or at least partly crystallized. The base slip contains water as dispersion medium with a content between 30% and 50% by weight and ultrafine SiO2 particles distributed, preferably colloidally therein, with a proportion between 50% and 70% by weight. The proportion of quartz glass particles in the formulation is in the range from 40% to 70% by weight and the proportion the multicomponent glass particles in the formulation is in the range from 5% to 37% by weight. The formulation can be used in a composite material. Firing aids can be made from the composite material.

Abstract: An LAS-glass for producing a transparent glass-ceramic and an LAS-glass-ceramic having a predetermined chroma C* and a predetermined visually determinable scatter value (S) are provided. The LAS-glass and LAS-glass-ceramic has a process window as large as possible during the nucleus formation process with respect to the residence time in the relevant temperature range for the formation of nuclei.
