Glass ceramic for chemical strengthening, chemically strengthened glass as well as application and electronic equipment of chemically strengthened glass

Abstract

The embodiment of the invention provides a glass ceramic for chemical strengthening and chemically strengthened glass prepared by performing ion exchange on the glass ceramic. In addition, the embodiment of the invention furthermore provides application of the chemically strengthened glass and electronic equipment comprising the chemically strengthened glass. The glass ceramic for chemical strengthening is sodium aluminum silicate glass containing ZrO2 crystals. The glass ceramic is transparent in a visible wavelength. The glass ceramic is excellent in properties such as hardness, breaking strength, breaking tenacity and the like, has excellent scratch resistance, dropping resistance and the like, and can be chemically strengthened. Therefore, the chemically strengthened glass with excellent properties, such as scratch resistance, dropping resistance and the like, can be obtained.

Problems solved by technology

[0010] For another example, although spinel glass-ceramics has certain mechanical strength, the content of alkali metal in this system is relatively small, and the carrier of ion exchange is relatively small; and most of the Al in this system 3+ The ions participate in the crystallization, the remaining content in the glass phase is less, and the glass structure is denser, so it is not conducive to ion exchange
