Beschreibung
Zusammenfassung:	The present invention provides a glass ceramic and a glass ceramic product which have excellent mechanical properties and low haze. The glass ceramic product comprises the following components in percentage by weight: SiO2: 60-80%; Al2O3: 3-15%; Li2O: greater than or equal to 5% but less than 10%; Na2O: 4-8%; P2O5: 0.5-5%; and ZrO2: greater than 5% but less than or equal to 15%, wherein (SiO2+Li2O)/(ZrO2+P2O5) is 4.0-15.5. By means of reasonable component design, the glass ceramic or glass ceramic product obtained by the present invention has excellent mechanical properties and low haze, and is suitable for a display device or electronic device having high optical property requirements. La présente invention propose une vitrocéramique et un produit vitrocéramique présentant d'excellentes propriétés mécaniques et un faible trouble. Le produit vitrocéramique comprend les composants suivants en pourcentage en poids : SiO2 : 60 à 80 % ; Al2O3 : 3 à 15 % ; Li2O : supérieur ou égal à 5 % mais inférieur à 10 % ; Na2
