Abstract

The invention provides glass. The glass comprises the following components in percentage by weight: 41-65.5% of SiO2, 17.5-31% of Al2O3, 5-14.5% of Li2O and Na2O, and 0.1-8% of P2O5, wherein a ratio of Li2O to (Li2O+Na2O) is 0.1-0.4. Through reasonable component design, the glass obtained in the invention is suitable for chemical strengthening and secondary hot working, and also has high Young modulus. A glass product obtained in the invention has high microscopic Vickers hardness and excellent mechanical properties.

Description

technical field [0001] The present invention relates to a kind of glass, especially relates to a kind of glass suitable for chemical strengthening, and the glass article made from it and its manufacturing method. Background technique [0002] In the prior art, glass materials are widely used in fields such as panels, backplanes, and structural materials of various electronic devices (such as mobile phones, smart watches, etc.). In the above application fields, the primary consideration of glass materials is drop resistance and impact resistance. For example, CN110040982A, CN110627365A and CN106232541A all disclose glass with excellent drop resistance. [0003] The impact resistance and scratch resistance of glass materials are not the same performance. For example, building a two-phase composite structure can effectively improve the impact resistance of the material, and increasing the hardness can improve the scratch resistance of the material. In some applications, the s...
