Abstract
The present invention relates to a spinel glass-ceramic made from a composition with the components 25 to 50% by weight SiO, 10 to 35% by weight AlO, 1 to 15% by weight MgO, 1 to 15% by weight PO, 1 to 25% by weight ZrOand/or TiO, 0 to 20% by weight LaO, 0 to 10% by weight BO, and 0 to 15% by weight additives. The spinel glass-ceramic contains at least one spinel phase, but no high quartz solid solution phase. The glass-ceramic according to the invention exhibits very high mechanical stability, for example, very high flexural strength, wherein its optical properties can be simultaneously adjusted. In addition, the present invention also relates to a method for producing and the use of the spinel glass-ceramic. Furthermore, the present invention relates to a shaped dental product containing the spinel glass-ceramic.
