Abstract

The invention provides a glass composition, the components of which are represented by mole percent, and the cation contains: Si 4+ : 35~57%; Al 3+ : 15~30%; Li + : 3~12%; Na + : 5~20%; P 5+ : 0.1-6%. Through reasonable component design, the glass composition obtained by the invention is suitable for chemical strengthening and secondary thermal processing. The chemically strengthened glass obtained by the invention has high micro-Vickers hardness, excellent scratch resistance and pressure resistance, and the scratch depth is low when impacted by sand dust and other substances with higher Mohs hardness, which is conducive to chemical strengthening The glass remains beautiful for a long time, reducing the possibility of 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...
