Abstract
(EN)
A glass ceramic for chemical strengthening and chemically strengthened glass prepared by performing ion exchange on the glass ceramic. Also provided are an application of the chemically strengthened glass and an electronic device 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 and breaking tenacity, has excellent scratch resistance, dropping resistance and the like. In addition, the glass ceramic may be chemically strengthened, so as to obtain the chemically strengthened glass with excellent properties such as scratch resistance and dropping resistance.

L'invention concerne une vitrocéramique pour le renforcement chimique et un verre chimiquement renforcé préparé par l'exécution d'un échange d'ions sur la vitrocéramique. L'invention concerne également une application du verre chimiquement renforcé et un dispositif électronique qui comporte le verre chimiquement renforcé. La vitrocéramique pour le renforcement chimique est un verre de silicate d'aluminium et de sodium contenant des cristaux de ZrO2. La vitrocéramique est transparente dans une longueur d'onde visible. La vitrocéramique présente d'excellentes propriétés telles que la dureté, la résistance à la rupture et la ténacité à la rupture, ainsi qu'en termes de résistance aux rayures, de résistance à la chute et autres. De plus, la vitrocéramique peut être chimiquement renforcée, de façon à obtenir un verre chimiquement renforcé possédant d'excellentes propriétés en termes de résistance aux rayures et à la chute.
