Glass Composition, Microcrystalline Glass, Preparation Method Therefor and Application Thereof

Abstract

Provided in the present application are a glass composition, microcrystalline glass and a preparation method therefor and application thereof. The glass composition includes, by mass percentage, 71.5-74.5% of SiO2; 6.2-8.7% of Al2O3; 1.7-3% of P2O5; 10-12.5% of Li2O; 0.1-2% of Na2O; and 3-5% of ZrO2. In the technical solutions of the present application, the components SiO2, Al2O3, P2O5, Li2O, Na2O, and ZrO2 in the glass composition are combined at a specific proportion, and in combination with a crystallization process and a strengthening process of microcrystalline glass, a b value and a haze can be significantly reduced, and the microcrystalline glass with excellent strengthening performance is thereby obtained.
