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 a preparation method for novel functional ceramics. The preparation method comprises the following steps of (1) preparing a bottom-layer base material; (2) preparing a middle-layer ceramics body; (3) preparing a surface-layer ceramics body; (4) carrying out laminating, preparing a blank and carrying out forming; and (5) carrying out sintering and forming. According to thepreparation method, a composite structure is adopted to prepare the ceramics, so that the use amount of zirconium and aluminum oxide is reduced, the cost is lowered, and the ceramics has good strength.

Description

technical field [0001] The invention belongs to the field of ceramic processing, and in particular relates to a preparation method of novel functional ceramics. 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 s...
