There is a need for a lithium silicate glass ceramic that can crystallize lithium disilicate at lower temperatures during the preparation of the lithium silicate glass ceramic. [Solution] Lithium silicate glass ceramics and glasses have been described that crystallize at low temperatures and contain oxides of certain divalent elements that are particularly suitable for dental materials. The present invention contains a divalent metal oxide selected from MgO, SrO, CaO, BaO, ZnO and mixtures thereof, and is particularly suitable for use in dentistry, preferably for dental restorations. Lithium silicate glass ceramic and glass suitable for preparation. [Selection figure] None |
