preparation example Construction

[0034] In this step, a ceramic case green body is provided. Specifically, the ceramic shell green body includes a ceramic substrate green body and a cover plate green body, the ceramic substrate green body has a through hole, and the cover plate green body is disposed in the through hole. Specifically, the preparation method of the ceramic shell green body is not particularly limited, for example, the ceramic shell green body formed by the ceramic substrate green body and the cover plate green body can be formed at one time through an injection molding process. Specifically, the first ceramic material and the second ceramic material can be injection-molded simultaneously through a two-color injection molding process, the first ceramic material can form a cover plate green body, and the second ceramic material can form a ceramic substrate green body. Thus, the ceramic case green body can be easily prepared. For example, after the ceramic substrate green body and the cover plat...

example 1

[0076] (1) 80 parts by weight of cubic phase zirconia powder containing zirconia powder of 80 wt%, 15 parts by weight of yttrium trioxide and 5 parts by weight of titanium dioxide are mixed to form the first ceramic material;

[0077] (2) Injection-molding the first ceramic material formed in the previous step, and performing degreasing treatment at 800°C, and then pre-sintering at 1300°C to obtain a pre-sintered green body for the cover plate. Cutting process to obtain the cover plate green body;

[0078] (3) Injection-molding the pre-configured second ceramic material including tetragonal zirconia, degreasing at 600°C, and then pre-sintering at 1000°C to obtain a calcined ceramic substrate. The ceramic substrate calcined body is cut to obtain a ceramic substrate green body with through holes;

[0079] (5) Place the cover plate green body prepared in the previous step in the through hole of the ceramic substrate green body to form a ceramic shell green body, and sinter the c...

example 2

[0082] Other modes of operation are the same as Example 1, and the difference is that in step (1), 90 parts by weight of zirconia powder containing 75wt% cubic phase zirconia, 10 parts by weight of diyttrium trioxide, 20 parts by weight of diyttrium trioxide, Cerium oxide and 10 parts by weight of titanium dioxide are mixed to form a first ceramic material.

Abstract

The application discloses a ceramic casing and a preparation method thereof as well as electronic equipment. Specifically, the application provides the ceramic casing. The ceramic casing comprises a ceramic substrate with a through hole and a cover plate which is positioned at the through hole and is integrated with the ceramic substrate; the cover plate is made of a first ceramic material; the light transmission rate of the cover plate is not smaller than 70 percent. Therefore, the bonding strength of the ceramic substrate and the cover plate is higher; in addition, the sealing property and the consistency of the ceramic substrate and the cover plate are better; the ceramic casing has good attractive effects and better use performance.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular, to a ceramic shell, a preparation method thereof, and an electronic equipment. Background technique [0002] With the improvement of consumption level, consumers not only pursue the diversification of functions of electronic products, but also have higher and higher requirements for their appearance and texture. In recent years, electronic equipment housings made of ceramic materials have become a research hotspot because of their mirror-like appearance, porcelain-like luster, good hand feeling, and good heat resistance. [0003] However, the current ceramic shells, their preparation methods, and electronic devices still need to be improved. Contents of the invention [0004] This application is based on the inventor's discovery and recognition of the following facts and problems: [0005] The inventors found that the current ceramic housing has problems such as po...
