摘要： A process for the production of a glass-ceramic comprises the following steps: a) providing a mixture comprising at least SiO2, Al2O3, BaO and TiO2, b) melting the mixture in order to produce a glass phase, c) cooling the glass phase, and d) ceramicizing the glass phase. In the process, the glass phase is heated over the course of at most 5 minutes, preferably over the course of at most 3 minutes, to a temperature in the region of the crystallization temperature of Ba1-xZ1xTi1-yZ2yO3, whereby Z1 is an element selected from the group consisting of Sr, Ca, Ce, Pb, La and Sm, whereby Z2 is an element selected from the group consisting of Zr, Hf, Nb, V, Y, Sc and Ta, and whereby x and y are each independently of one another 0≦x,y≦0.5, preferably 0≦x,y≦0.1, but substantially below the crystallization temperature of Ba[Al2Si2O8].

摘要： The transparent glass ceramic with low thermal expansion is produced from a glass that is fined with a combination of environmentally friendly fining agents, specifically a combination of SnO2 with at least one of Sb2O3, SO42−, Br− and Cl−. The glass is free of arsenic and is preferably made from a mixture of SiO2, Al2O3, Li2O, TiO2, ZrO2 and ZnO. A mirror support for astronomy and a prism for LCD lithography are advantageously made from this glass ceramic.
