Problems solved by technology

[0003] When processing existing ceramics, molds are often used after mixing materials. In order to improve certain properties of ceramics, corresponding additives are often added to improve the properties of materials. However, when certain properties are required on a certain side of ceramics, for example, In the preparation of ceramics, it is often required that the inner layer has good strength and corrosion resistance, and the surface layer needs to have better coloring stability. The ceramics prepared by the conventional firing method after lamination are prone to cracking, and the yield is low. meet performance needs

Abstract

The invention relates to anti-cracking composite ceramic. The anti-cracking composite ceramic is prepared from a bottom-layer base material, a middle-layer base material and a surface-layer base material. According to the prepared anti-cracking composite ceramic, the base material is prepared by compounding three raw materials with different formulas, the bottom-layer raw material has good strength and corrosion resistance, the stability and the use strength of formed porcelain can be supported, the middle-layer base material has good connecting and complexing functions, the connection stability for the bottom layer and the surface layer is achieved, the surface-layer material has good strength and hardness and has a good adsorption effect on substances in a pigment, and the use stabilityof the material and the stability of the formed color can be effectively improved.

Description

technical field [0001] The invention belongs to the field of ceramic processing, and in particular relates to a crack-resistant composite ceramic. Background technique [0002] Ceramics is a traditional vessel material in our country. With the development of modern science and technology, many new ceramic varieties have appeared in the past century. They no longer use or rarely use traditional ceramic raw materials such as clay, feldspar, and quartz, but use other special raw materials, and even expand to the scope of non-silicate and non-oxide, and many new processes have emerged. Ceramic materials can now be used as a general term for various inorganic non-metallic solid materials. [0003] When processing existing ceramics, molds are often used after mixing materials. In order to improve certain properties of ceramics, corresponding additives are often added to improve the properties of materials. However, when certain properties are required on a certain side of ceramic...
