摘要： A ceramic material for improving surface adhesion of dental zirconia, a restorative material and a preparation method and a pasting method thereof are provided. The ceramic material includes SiO2, B2O3, GeO2, Al2O3, Li2O, Nb2O5, Na2O, ZrO2, P2O5, and a rare earth oxide. The ceramic material contains GeO2, on one hand, GeO2 can replace SiO2 in the ceramic material, thereby reducing the high-temperature melting temperature of glass, and saving the production cost, and on the other hand, GeO2 can effectively reduce the ratio of Si to Li, such that fine and uniform lithium disilicate crystals are formed after crystallization, and the adhesion strength with a zirconium oxide matrix is improved.

摘要： This application relates to the technical field of electronic products, and in particular, to curved glass and a preparation method therefor, and an electronic device. A molding process from a high temperature to a low temperature can be reduced, and a preparation process can be shortened. Therefore, a resource waste caused by a high temperature to a low temperature in a related technology can be reduced, and manufacturing costs are reduced. This application provides a preparation method for curved glass, including: 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.

摘要： A pre-sintered porcelain block for dental restoration; the pre-sintered porcelain block does not contain crystal phases and has a Vickers hardness of 0.5-2 GPa. Due to a hardness which is significantly lower than that of the porcelain block containing a lithium metasilicate crystal phase, the pre-sintered porcelain block may be processed by using dry machining and can simultaneously be processed by using wet machining when being mechanically processed into a dental restoration shape.

摘要： A glass substrate and a method for manufacturing the glass substrate are provided. The glass substrate may include a base glass including Si0 2 , Al 2 O 3 , and Li 2 O, and nanocrystals having an average diameter in a range from about 5 nm to about 10 nm, thereby exhibiting enhanced surface strength properties while maintaining good transmittance properties. The method may include a step of heat-treating a base glass, thereby providing a glass substrate having enhanced strength properties.
