Lithium disilicate-apatite glass ceramic containing transition metal oxide

摘要

Lithium disilicate-apatite glass ceramics containing transition metal oxides, characterized by high chemical stability and whose translucency can be adjusted as desired, and thus can be used in particular as a restorative material in dentistry, be written. The lithium disilicate-apatite glass ceramic according to the invention comprises a divalent oxidation comprising lithium disilicate as the main crystal phase and apatite as the further crystal phase and selected from the group of CaO, SrO and mixtures thereof And a transition metal oxide selected from the group of transition metal oxides having atomic numbers 39 to 79 and mixtures thereof, wherein the molar ratio of divalent oxide to transition metal oxide Is in the range of 1.0 to 20.0, in particular 1.0 to 17.0, preferably 1.5 to 16.5.
