Abstract

The invention relates to the technical field of microcrystalline glass, and provides high-strength transparent microcrystalline glass which comprises the following components in percentage by mass: 55%-75% of SiO2, 4%-10% of Al2O3, 8%-14% of Li2O, 5.1%-8% of Na2O, 1.5%-5% of P2O5, 2%-10% of ZrO2, 0.2%-0.8% of Sb2O3 and 0.2%-1.0% of CeO2. Through component design and microcrystallization process regulation and control, the obtained microcrystalline glass material has excellent mechanical properties and optical properties, can be further chemically strengthened to improve the mechanical properties, and is suitable for electronic equipment or display equipment.

Description

technical field [0001] The invention relates to the technical field of glass-ceramic, in particular to a high-strength transparent glass-ceramic and a preparation method. Background technique [0002] As a transparent material with excellent mechanical properties and optical properties, glass materials are widely used in mobile smart terminal devices, such as mobile phones, smart watches, tablets and personal computers and other portable electronic devices. Glass is also used to protect its internal electronic components. However, the glass material may be scratched or damaged by impact when it is contacted by hard objects, which requires the glass to have excellent mechanical properties to avoid damage during use and protect the equipment. In the past, glass used to protect mobile and portable smart electronic devices and automotive display covers often required chemical strengthening, but this kind of glass is prone to cracks perpendicular to the glass surface. Normal us...
