Abstract

The invention provides a glass composition. The glass composition comprises the following components in percentage by mole: in terms of cations, 35-57% of Si<4+>, 15-30% of Al<3+>, 3-12% of Li<+>, 5-20% of Na<+>, and 0.1-6% of P<5+>,. Through reasonable component design, the glass composition obtained by the invention is suitable for chemical strengthening and secondary hot working. Chemically-strengthened glass obtained in the invention has high microscopic Vickers hardness and excellent scratch resistance and pressure resistance, and has low scratch depth when being impacted by sand and dustand other substances with higher Mohs hardness, which is helpful for keeping the chemically strengthened glass beautiful for a long time and reducing the possibility of a protection failure.

Description

technical field [0001] The invention relates to a glass composition, in particular to a glass composition suitable for chemical strengthening, and a chemically strengthened glass made therefrom. Background technique [0002] Chemically strengthened glass is widely used in the fields of panels, backplanes, and structural materials of various electronic devices (such as mobile phones, smart watches, etc.). In the application areas mentioned above, the primary consideration for chemically strengthened glass 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...
