Characteristics of Advanced Ceramic Material Preparation Technology

The preparation technology of advanced ceramic materials has been continuously explored and summarized on the basis of traditional ceramic preparation technology. Generally speaking, the preparation process of traditional ceramics is relatively stable, with a focus on efficiency, quality control, and other aspects. The requirements for material microstructure are not very strict, while advanced ceramics must take many special measures in powder preparation, molding and sintering, and control the material microstructure to obtain high-performance advanced ceramic products. For other materials such as metal and organic polymer materials, the preparation process goes through a liquid phase process, and the density of the material is generally not a problem, that is, the material does not contain pore defects. As inorganic non-metallic materials, the preparation process of single crystal and glass materials must also go through a liquid phase process, and there is no problem of pores. However, ceramic materials generally must undergo the sintering process of porous green bodies (with a porosity of up to 50%). For advanced ceramics, the sintering process is accompanied by multiple factors such as densification, grain growth, grain boundary formation, and changes in gas particle size, and these factors interfere with each other. The performance of the final fired product is not only related to the sintering process, but also closely related to the properties of the pre fired green body and powder. It can be seen that the performance of advanced ceramic materials strongly depends on the process.

Traditional ceramic materials_ T art is basically experiential. Although modern science and technology are increasingly widely used in the manufacturing process of traditional materials, due to historical reasons, traditional ceramic techniques have long relied on experience to shape them. The manufacturing process of modern advanced ceramic materials itself and its various steps not only contain a large amount of modern technology content, but also the determination of the process and quality monitoring depend on the progress of modern science and technology.
