Abstract: A curved glass and a preparation method is provided. The preparation method for curved glass includes: melting a glass batch into a glass liquid, and clearing the glass liquid; introducing the cleared glass liquid into a mold cavity with a preset shape, and forming, by using a compression molding process, a glass product with a shape corresponding to that of the curved glass, where a size of the glass product is greater than a size of the curved glass; annealing the molded glass product; and processing the annealed glass product into the curved glass based on the shape and the size of the curved glass.

Abstract: This application provides phase-separated glass prepared from basic glass through phase separation. This application to further provides tempered glass prepared from basic glass by sequentially performing phase separation and chemical strengthening. This application further provides a method for preparing the phase-separated glass, a method for preparing the tempered glass, a housing that is of an electronic device and that includes the phase-separated glass or the tempered glass, a display of an electronic device, and an electronic device. In this application, phase separation is performed on the basic glass to form two-phase mixed phase-separated glass that includes an alkali-boron-rich separated phase and a silicon-rich separated phase. The phase-separated glass can prevent micro-cracks in the glass from propagating, thereby improving mechanical properties such as fracture toughness of the glass and then improving anti-drop performance of the glass. Experimental results show that compared with glass without phase separation, the phase-separated glass according to the present invention improved the fracture toughness by 20% or more, and increased a ball drop height by 30% or more. In addition, the phase separation did not affect transparency and transmittance of the glass.
