Abstract
The invention discloses a glass plate and a manufacturing method thereof. The glass plate comprises a first surface and a second surface which are opposite to each other. The glass plate is a multi-phase complex formed by a microcrystalline phase and a glass phase, and the ratio of the microcrystalline phase to the glass phase in the glass plate tends to be increased in a gradient mode from the first surface to the second surface. When the glass plate provided by the invention is manufactured into a glass cover plate of electronic equipment, the first surface can be manufactured into the outersurface of the glass cover plate, and the second surface can be manufactured into the inner surface of the glass cover plate. In the glass substrate, from the first surface to the second surface of the glass plate, the ratio of the microcrystalline phase to the glass phase in the glass plate tends to increase in a gradient manner. Therefore, the electronic equipment glass cover plate made of theglass plate provided by the invention has relatively high intrinsic strength and relatively high drop resistance, so that the drop resistance of the electronic equipment is improved.
Description
technical field [0001] The present application relates to the technical field of electronics and communication, in particular to the technical field of drop-resistant housing. Background technique [0002] With the continuous improvement of consumers' requirements on the drop resistance of electronic devices such as mobile phones, it is required that the glass cover used in the electronic devices should have good drop resistance. [0003] In recent years, chemically strengthened glass has become the mainstream trend for the glass cover of electronic equipment, because after the glass is "chemically strengthened" or "tempered", a certain depth of compressive stress layer is formed on the glass surface, thereby improving the strength and resistance of the glass. Falling sex. [0004] However, in view of the ultra-thin trend of the glass cover, the current mature chemical strengthening and physical strengthening process methods have been unable to significantly improve the str...
