To provide glass ceramic.SOLUTION: The invention relates to glass ceramic having extremely good mechanical and optical properties, especially capable of being used as a dental repairing material, and having SiOas a major crystal phase, and a precursor thereof. The glass ceramic exhibits an advantageous combination of desired mechanical and optical properties as the dental repairing material, and can provide a desired shape by a desired method as a dental material unexpectedly. It is further preferable that the glass ceramic contains 2.8 to 9.0 wt.% of LiO.SELECTED DRAWING: None 【課題】ガラスセラミックを提供すること。【解決手段】本発明は、非常に良好な機械的および光学的性質によって特徴付けられ、かつ特に歯科の修復材料として使用することができる、主要な結晶相としてＳｉＯ２を有するガラスセラミック、およびそれらの前駆体に関する。このガラスセラミックは意外にも、修復用歯科材料として望ましい機械的および光学的性質の有利な組合せを呈し、かつ歯科材料として望ましい方法で所望の形状を与えることもできる。このガラスセラミックが２．８〜９．０ｗｔ％のＬｉ２Ｏを含むことはさらに好ましい。【選択図】なし
